Congratulations on your purchase of the Orion IntelliScope™ Com-puterized Object Locator. When used with any of the SkyQuestIntelliScope XT Dobsonians, the object locator (controller) will pro-vide quick, easy access to thousands of celestial objects for view-ing with your telescope.The controller’s user-friendly keypad combined with its database of more than 14,000celestial objects put the night sky literally at your fingertips. You just select an object toview, press Enter, then move the telescope manually following the guide arrows on theliquid crystal display (LCD) screen. In seconds, the IntelliScope’s high-resolution, 9,216-step digital encoders pinpoint the object, placing it smack-dab in the telescope’s field ofview! Easy!
Compared to motor-dependent computerized telescopes systems, IntelliScope is faster,quieter, easier, and more power efficient. And IntelliScope Dobs eschew the complex ini-tialization, data entry, or “drive training” procedures required by most other computerizedtelescopes. Instead, the IntelliScope setup involves simply pointing the scope to twobright stars and pressing the Enter key. That’s it — then you’re ready for action!
These instructions will help you set up and properly operate your IntelliScope Computer-ized Object Locator. Please read them thoroughly.

Parts ListYour IntelliScope™ Computerized Object Locator comes with the following parts:
Qty. Description
1 Object locator computer (controller)
1 Altitude encoder assembly
1 Coil cable
1 Altitude encoder cable (53" long)
1 Azimuth encoder cable (24" long)
6 Wire retaining clips
2 Hook-and-loop strips (1 “hook” strip, 1 “loop” strip)
1 Plastic bumper
3 Wood screws
2 Nylon washers
1 9-volt battery
The only tool needed for installation is a Phillips-head screwdriver. Remove the opticaltube from the base to begin installation.
Note: The IntelliScope Computerized Object Locator is only compatible with Orion Sky-Quest XT IntelliScope Dobsonians. If you have another Dobsonian, or any other tele-scope, the IntelliScope system will not function properly.
1. Installation1) Install the altitude encoder assembly onto the base’s right side panel. This is the side
of the base opposite the side with the IntelliScope Computerized Controller Port.Below the 5/8" through-hole in the panel, there are two predrilled starter holes in theinwardfacing surface (Figure 2).Take two of the supplied wood screws and push themthrough the two slotted holes in the bottom of the altitude encoder’s computer board.The screw heads should be on the same side as the altitude encoder’s modular jack.Now, with the screws pushed through the encoder board, place a nylon washer onthe end of each screw (Figure 3). Then, thread the screws into the starter holes in theside panel. The shaft on the altitude encoder assembly should protrude through the5/8" through-hole in the side panel. It will take a bit of dexterity to keep the washerson the ends of the screws when installing, so don’t get frustrated if it takes a coupletries. The screws should not be fully tightened; they should be tight, but not tightenough to prevent the altitude encoder from moving up and down within the slots inthe encoder board.
2) There is a pilot hole above the 5/8" through hole in the right side panel’s interior sur-face; this is where the plastic bumper that protects the altitude encoder assembly willbe installed. Take the remaining wood screw, push it through the bumper, and threadit into the pilot hole until tight (Figure 4).
3) Connect one end of the azimuth encoder cable (the shorter of the two cables) to theencoder jack in the top baseplate of the Dobsonian base. Connect the other end to the
4
encoder connector board that should bealready installed on the base’s left sidepanel. The cable should plug into the jackon the left side of the encoder connectorboard (see Figure 5).
4) Connect one end of the altitude encodercable to the modular jack on the altitudeencoder assembly. Connect the other end ofthe cable to the jack on the right side of theencoder connector board (see Figure 5).
5) Use the provided wire clips to secure thealtitude and azimuth cables neatly to thebase. We recommend using two clips forthe (shorter) azimuth cable, and four clipsfor the (longer) altitude cable (Figure 5a.).The clips have adhesive backing; simplypeel the paper off the back of the clip andpress the adhesive back to the base whereyou want the clip to be located.
6) Place the telescope optical tube into thebase. Be very careful not to hit the altitudeencoder with the side bearing on the tubewhen doing this or damage to the encodercould result. The bumper helps to preventsuch contact.
7) Reinstall the telescope’s tensioning knob(the one with the Teflon and metal washers)through the base’s left side panel (the sidethat has the IntelliScope ComputerizedController Port label) and into the threadedhole in the center of the tube’s side bearing.
8) Reinstall the telescope’s retaining knob,without its black nylon bushing, through thealtitude encoder’s aluminum shaft (nowprotruding from the right side panel) andinto the tube’s side bearing (Figure 6).Make sure this knob is fully tightened.
9) Insert one end of the coil cable into thelarger of the two jacks on the top of theIntelliScope controller (Figure 1). Insert theother end into the “IntelliScopeComputerized Controller Port” on the leftside of the Dobsonian base.
10) Two hook-and-loop strips (one strip of“hooks” and one strip of “loops”) have beenprovided to hang the IntelliScope controllerin a convenient location on the base whennot in use. Place the “hooks” strip on the

back of the controller, and the “loops” stripon the base in a convenient spot. Makecertain the location of the strip on the basewill not cause the controller to interferewith the motions of the mount. You maywant to consider using the optional holsterinstead of the supplied hook-and-loopstrips. The holster is a metal holder cus-tom-designed to fit the IntelliScope con-troller. When installed at the top of theDobsonian base, it provides a firm mount-ing for the controller at a convenient posi-tion for easy access. The controller can beremoved from the holster when needed orkept in the holster during use.
11) Slide the battery cover off the back ofthe hand control and insert the 9-volt alka-line battery. Make sure the positive andnegative terminals of the battery are ori-ented as shown in the bottom of the bat-tery compartment. Replace the batterycover.
Your IntelliScope Computerized ObjectLocator is now installed and ready to beused.

2. AlignmentThis section will familiarize you with the alignment procedure for the IntelliScope system.
Powering the ControllerTo turn the controller on, firmly press the Power button. The LED lights will activate andthe LCD screen will display its introduction message. The intensity of the illumination canbe adjusted by repeatedly pressing the Power button. There are five levels of LED bright-ness. Choose a brightness level that suits your conditions and needs. (Dimmer settings willprolong battery life.)
To turn the controller off, press and hold the Power button for a few seconds, thenrelease it.
To conserve battery life, the controller is programmed to shut itself off after being idle for15 minutes. So, make sure to press a button at least once every 15 minutes if you do notwant the controller to turn off. If the controller does turn off, you will need to perform theinitial alignment procedure again.If the LCD screen and the buttons’ backlighting automatically begin to dim, it’s time tochange batteries.
Initial Vertical AlignmentAfter powering up the controller, the top line of the LCD display will read: “POINT VER-TICAL.” If the vertical stop you installed on the Dobsonian base during assembly of thetelescope is properly adjusted (see below), simply rotate the telescope upwards in alti-tude until the bottom of the tube comes into contact with the vertical stop. Once the tele-scope tube is in the vertical position, press the Enter button to start the two-star align-ment procedure.
Adjusting the Vertical StopIn order for the IntelliScope system to work accurately, the vertical stop must be precise-ly adjusted so that the optical tube is truly perpendicular to the azimuth axis of the basewhen the controller says “POINT VERTICAL.” For most IntelliScopes, the vertical stopmust use the nylon spacer, one of the 1/16"-thick washers, and the 1/32"-thick washersto achieve this. These parts, plus an extra 1/16"-thick washer are supplied with theDobsonian base. If you do not have access to a carpenter’s level, then using the spacer,1/16"-thick washer, and 1/32"-thick washerwill be the best you can do to adjust the ver-tical stop.
For the most precise adjustment of the verti-cal stop (which will allow the best pointingaccuracy to be achieved), you should use acarpenter’s level. Any hardware store willhave one. First, make sure the base itself islevel. Place the carpenter’s level on the topground board and rotate the base 180˚ inazimuth (Figure 7). The level should indi-cate that the base is level through theentire rotation. If not, then reposition thebase on the ground, or place shims under-neath the feet until the base stays levelthough a 180˚ rotation.
7
Figure 7. Place a carpenter’s level on thebase as shown. The base should stay levelthrough a 180˚ rotation in azimuth. Once thevertical stop is set, the base does not need tobe level to function properly.
Next, place the nylon spacer, the 1/16"-thickwasher, and the 1/32"-thick washer on thevertical stop screw, and thread the entireassembly into the insert in the base’s frontbrace. Now, rotate the telescope upwards inaltitude until the mirror cell of the telescopecomes into contact with the vertical stop.Place the carpenter’s level across the top ofthe telescope (see Figure 8). Is the top ofthe tube level? If so, you are finished adjust-ing the vertical stop. If not, add or remove awasher to the vertical stop screw until thetop of the tube is level when the mirror cellcomes into contact with the vertical stop.
Once the vertical stop is accurately adjust-ed, it should not need adjustment again.The base does not need to be level for theIntelliScope system to function properly; thebase only needs leveling when initially setting the vertical stop.
Simple Two-Star AlignmentAfter setting the vertical position of the optical tube, a simple two-star alignment processis all that is needed to ready the IntelliScope system for operation. This is a great simpli-fication from other computerized systems, which require you to enter data such as yourlongitude, latitude, and time zone. For the IntelliScope controller to accurately findobjects, you only need to center two bright stars in your telescope and indicate to the con-troller which two stars you have centered. This is quite easy to do. For your convenience,we have provided finder charts for the alignment stars in Appendix B. Use the finder chartto locate and identify two bright stars in your current night sky. For best results, choosetwo stars that are at least 60˚ apart from each other. (The width of your fist at arm’s lengthis about 10˚, so you want the stars to be at least six fist-widths apart.)
So, the optical tube is now in the vertical position and you’ve chosen two bright stars inthe sky to use for alignment. The telescope should have a high power eyepiece, such asthe 10mm Sirius Plössl, in the eyepiece holder and the finder scope should be properlyaligned with the telescope (these procedures are described in your telescope’s manual).The LCD screen will state on its top line “ALIGN STAR 1,” with the name of a star flash-ing on the second line.
Use the arrow buttons to scroll through the names of the alignment stars. The up arrowbutton scrolls through the stars alphabetically from A to Z. The down arrow button scrollsalphabetically backwards, from Z to A. When you arrive at the name of the star you wishto align on, you can begin to move the telescope so that it is pointing at that star (but don’tpress the Enter button yet).
Note: The controller will not accept Polaris as the first alignment star. This helps preventthe pointing accuracy from decreasing over time. It is OK to use Polaris as the secondalignment star, however.
Take hold of the “navigation knob” on the optical tube and move the telescope so that itis pointing in the general area of the alignment star. Aim the telescope so the alignmentstar appears in finder scope. Be careful not to confuse the alignment star with other starsin the area when doing this. (It will likely be the brightest star in the field of view.) Now,

move the telescope until you have centered the star on the crosshairs of the finder scope.Look into the eyepiece of the telescope, and you should see the alignment star in the fieldof view of the eyepiece. If it isn’t, then your finder scope is out of alignment with your tel-escope and will need to be adjusted. Once the alignment star is in the eyepiece’s field ofview, center it in the eyepiece as best you can by making small movements to the tele-scope. (If you have one, an illuminated reticle eyepiece is great for centering alignmentstars). Once this is done, press the Enter button on the controller. You have now com-pleted one-half of the two-star alignment.
The LCD screen will now read “ALIGN STAR 2” on the first line with an alignment star’sname flashing on the second line. As before, scroll through the names of the stars withthe arrow buttons until you reach your second chosen alignment star. Repeat the proce-dure described above for your second alignment star. When you have aligned on the sec-ond star, press the Enter button. The LCD will then display a number. It is the alignmenterror factor, or “warp” (W) factor.
The Alignment Error (Warp) FactorThe “warp” alignment error factor essentially lets you know if your alignment was accu-rate or not. Ideally, this number should be as low as possible, but any “W” of 0.5 or small-er is acceptable (regardless of + or - sign). Warp factors of ±0.3 and ±0.4 are the mostcommon. Warp factors under ±0.2 are typically not achievable. If you complete an align-ment and the warp factor is larger than ±0.5 (e.g., +0.6, -0.6, +0.7, -0.7, etc.), then youmust turn the controller off (by holding down the Power button) and begin the alignmentprocedure again. Otherwise, there is no guarantee that the controller will consistentlyplace objects within the field of view of a medium-low power eyepiece.
An unacceptable warp factor may indicate that you aligned on the wrong star or did nothave the telescope initially in a precisely vertical position. If you are having problems get-ting the warp factor at or below ±0.5, see the troubleshooting section in Appendix A.
Your IntelliScope Computerized Object Locator is now ready to find objects. Replace thehigh- powered eyepiece you used for centering the alignment stars with a low-power,wide-field eyepiece, such as the 25mm Sirius Plössl.
3. Overview of ControllerThe IntelliScope Computerized Object Locator has been specifically designed for ease ofuse.This section will help familiarize you with the basic layout and operation of the controller.
PushbuttonsBesides the Power, Enter, ID, FCN, and up/down arrows, all pushbuttons have letters onthem with numbers above them. The letters designate the function of the pushbutton. Thenumbers above them are used for entering numerical data only; the numbers are neveractive until a function is first chosen. The numbers are arranged like a telephone keypadfor ease of number entry. None of the function buttons will work properly until an initialalignment, as outlined previously, is completed. If you press a function button before thetwo-star alignment is completed, the controller will display “MUST STAR ALIGN.” Turn theunit off, then on again (by using the Power button), to begin the alignment routine again.
The Guide ArrowsThe controller leads you to astronomical targets with guide arrows displayed on the LCDscreen. After an object is selected to view, you will see two guide arrows, one that points
9
left or right, and one that points up or down.Move the telescope tube in the correspon-ding direction of the guide arrows. If youare standing to the left of the telescope andfacing the same direction the telescope ispointed, the guide arrows will exactly corre-spond with the direction you should movethe telescope (Figure 9). Otherwise, if anup arrow is displayed, move the telescopetube upward, if a down arrow is displayed,move the telescope tube downward, if a leftarrow is displayed, rotate the telescopecounterclockwise, and if a right arrow isdisplayed, rotate the telescope clockwise.There is a number next to each guide arrowthat indicates how far the telescope needsto be moved to reach the selected object.As you move the telescope toward theobject, this number will decrease. Whenthe number goes below ten, the figure willbe displayed in tenths; this helps to makesmall, precise movements to the telescopetube in order to bring the object into yourfield of view. When both numbers reach zero, stop moving the telescope. The object willbe within the field of view of a medium-low power eyepiece (25mm focal length or longer).
For example, look at Figure 10a, which shows an LCD screen for someone trying tolocate M51, otherwise known as the Whirlpool Galaxy. The first arrow is pointing right andgives a number of 34. The second arrow is pointing up and displays the number 12. Thismeans that the telescope tube should be moved to the right (clockwise) and up. Whenyou are close to M51, the numbers will be displayed in tenths, as is shown in Figure 10b.When the numbers reach zero (Figure 10c), the telescope will be pointed right at theWhirlpool Galaxy.
10
Figure 10a-c. This sequence of pictures illustrate how the controller’s guide arrows will lookas you are finding an object. (a.) When you are far away from the object, there will be a number(from 10 to 179) to the left of the guide arrows. (b.) When you are close to the object, each guidearrow will display a number on its immediate left (from 0 to 9) and immediate right (from 0 to 9);the number on the left is whole number increments, while the number on the right is in incrementsof tenths. This helps in making small movements to the telescope to pinpoint the object’s location.(c.) When the guide arrows display “0.0 0.0”, the object will be within the field of view of thetelescope (with a 25mm or longer focal length eyepiece).
a. b. c.
Figure 9. If you stand to the left of thetelescope, and face the direction the tube ispointing, the guide arrows will correspondexactly with the direction you should move thetelescope in order to find the selected object.
It is easiest to move the telescope in one direction at a time (say altitude) until the corre-sponding number reached “0.0”. Then move the scope in the other direction (azimuth)until that number also reads “0.0”.
If the object selected to view is currently located below the horizon, the word “HORIZON”will flash before the guide arrows are displayed. Choose another object to view.
4. Locating the PlanetsBy far the most popular objects for viewing, after the Moon, are the planets. Since theother eight planets in our solar system are also orbiting the Sun, they do not appear infixed positions in the night sky like deep-sky objects and stars do. Because of this, thecontroller requires you to input the date before it can find the planets.
To find planets with your IntelliScope Computerized Object Locator, use the followingprocedure:
1) Press the Planet button on the controller.
2) The LCD screen will display a date similar to the following:
DATE 01 JUN 2003
3) The number after the word “DATE” will be flashing and represents the day of themonth. Input the two-digit day using the number buttons.
4) The three-letter month will now be flashing. Use the arrow buttons to scroll to thepresent month and then press the Enter button.
5) Now the year will flash. Input the year using the number buttons.
If you make a mistake while inputting the date, press the Enter button at any time whilestill within the Planet button function. The LCD screen will then display the last dateinput, with the two-digit day after the word “DATE” flashing. Input the correct date as out-lined above.
Now, to choose a planet to view, press the arrow buttons and scroll through the planets.The planet’s name will be displayed in the upper left section of the LCD screen, with theguide arrows on the upper right of the LCD screen. Move the telescope in the corre-sponding direction shown by the guide arrows.
The lower left screen shows the constellation that the planet appears in, with its presentco-ordinates given in right ascension and declination. When you are finished viewing theplanet, you may scroll to another planet by using the arrow buttons.
The features and details you can see will vary from planet to planet. The followingdescriptions give a brief overview of what to expect when viewing them:
MERCURY Mercury is often so close to the Sun that it cannot be seen. Sometimes it isvisible for a brief period after the Sun sets, and sometimes it’s visible in the morning justbefore the Sun rises. Mercury does not really show any detail, but is quite bright. Withyour telescope, you will be able to investigate this planet’s orange-colored hue. LikeVenus, Mercury sometimes appears as a crescent, rather than as a full disk.
VENUS At its brightest, Venus is the most luminous object in the sky, excluding the Sunand the Moon. It is so bright that sometimes it is visible to the naked eye during full day-light! Ironically, Venus appears as a thin crescent, not a full disk, when at its peak bright-ness. Because it is close to the Sun, it never wanders too far from the morning or evening
11
horizon. No surface markings can be seen on Venus, which is always shrouded in denseclouds.
MARS The Red Planet makes its closest approach to Earth every two years. Duringclose approaches you’ll see a red disk, possibly some light and dark regions, and maybethe polar ice cap. To see surface detail on Mars, you will need a high power eyepieceand very steady air!
JUPITER The largest planet, Jupiter, is a great subject for observation. You can see thedisk of the giant planet and watch the ever-changing positions of its four largest moons— Io, Callisto, Europa, and Ganymede. Higher power eyepieces should bring out thecloud bands on the planet’s disk and maybe even the Great Red Spot.
SATURN The ringed planet is a breathtaking sight when it is well positioned.The tilt angleof the rings varies over a period of many years; sometimes they are seen edge-on, whileat other times they are broadside and look like giant “ears” on each side of Saturn’s disk.A steady atmosphere (good seeing) is necessary for a good view. You will probably seea bright “star” close by, which is Saturn’s brightest moon, Titan.
URANUS Uranus is a faint planet, and requires high powers (at least 100x) before itstarts to show any detail that distinguishes it from stars. Uranus will appear as a pale,blue-green disk.
NEPTUNE Like Uranus, Neptune will require high powers before showing anything to dis-tinguish itself from stars. Neptune will appear as a bluish-colored disk, possibly with avery faint moon nearby if you are using a larger-aperture IntelliScope.
PLUTO Smaller than our own Moon, Pluto is very, very faint and shows little more thana point of light similar to a star. Even the Hubble Space Telescope is unable to showmuch detail on Pluto. Many amateur astronomers note how Pluto moves with respect tobackground stars (over several nights) in order to confirm their observation of our mostremote planet.
5. Locating Deep-Sky Objects byCatalogCatalogs are groups of deep sky objects of interest that have been assembled and givendesignations. Very often a deep-sky object will have a catalog number, as well as a “com-mon” name. For example, the Orion Nebula is listed in the Messier catalog as “M42.” Thecontroller has three catalogs built-in: The Messier catalog (M), the New General Catalog(NGC), and the Index Catalog (IC). Many of the objects in the Messier catalog also haveNGC catalog designations.
The Messier CatalogThe Messier catalog contains 110 galaxies, nebulas, and star clusters identified by thefamous French astronomer Charles Messier and his colleagues in the late 1700’s. Theseare some of the most popular celestial attractions observed by amateur astronomers.
To view an object from the Messier catalog, press the M button. Then enter the numberof the Messier object you wish to view using the numeric buttons and press the Enterbutton. For example, to view Messier 57, also known as “the Ring Nebula,” you wouldpress the M button, then press the “5” button, then press the “7” button, followed by theEnter button. If the number of the Messier object you wish to view contains three digits,it is not necessary to press Enter after inputting the third digit.
12
The object’s catalog designation will be shown in the upper left corner of the displayscreen, with the guide arrows in the upper right. The lower left will display the constella-tion the object resides in and the object’s common name (if it has one) or a brief descrip-tion of the object. Move the telescope in the corresponding directions shown by the guidearrows to locate the object.
You can get more information about the selected object by pressing the Enter button.The second line of the LCD display will then cycle information about the object you areviewing such as its celestial coordinates (R.A. and Dec.), magnitude (brightness), size (inarc-minutes or arc-seconds), and a brief scrolling text description.
When you are finished viewing the selected Messier object, you may scroll to anotherMessier object by using the arrow buttons, or you can select another Messier object toview by pressing the M button again.
The New General CatalogThe New General Catalog, or NGC, is a catalog of some 7,840 deep-sky objects com-piled by the Danish astronomer J. L. E. Dreyer more than 100 years ago. It contains hun-dreds of excellent examples of each type of deep-sky object and is the most well knownand used catalog by amateur astronomers beyond the already mentioned Messier cata-log. To be more precise, the version of the New General Catalog used in the IntelliScopeComputerized Object Locator is an improved version known as the “Revised NewGeneral Catalog”; this version has many corrections from Dreyer’s original list.
To view an object from the NGC catalog, press the NGC button. Then enter the numberof the NGC object you wish to view using the numeric buttons and press Enter. For exam-ple, to view the Andromeda Galaxy, which is listed as NGC224, you would press the NGCbutton, then the “2” button twice, then the “4” button, followed by the Enter button. If thenumber of the NGC object you wish to view contains four digits, it is not necessary topress Enter after inputting the fourth digit.
The object’s catalog designation will be shown in the upper left corner of the LCD screen,with the guide arrows in the upper right. The lower left will show the constellation theobject resides in, and the object’s common name (if it has one) or a brief description ofthe object will be shown in the lower right. Move the telescope in the corresponding direc-tions shown by the guide arrows.
You can get more information about the selected object by pressing the Enter button.Thesecond line of the LCD display will then cycle information about the object you are view-ing such as its celestial coordinates (R.A. and Dec.), magnitude (brightness), size (in arc-minutes or arc-seconds), and a brief scrolling text description.
When you are finished viewing the selected NGC object, you may scroll to another NGCobject by using the arrow buttons, or you can select another NGC object to view by press-ing the NGC button again.
The Index CatalogThe Index Catalog, or IC, contains 5,386 objects discovered in the decade or so after theNGC catalog was first published. This list contains objects similar to the NGC, but ICobjects are typically fainter and more difficult to observe.
To view an object from the IC catalog, press the IC button. Then input the number of theIC object you wish to view using the numeric buttons and press the Enter button. Forexample, to view the Flaming Star Nebula, which is listed as IC405, you would press theIC button, then the “4” button, then the “0” button, then the “5” button, followed by the
13
Enter button. If the number of the IC object you wish to view contains four digits, it is notnecessary to press Enter after inputting the fourth digit.
The object’s catalog designation will be shown in the upper left corner of the LCD screen,with the guide arrows in the upper right. The lower left will show the constellation theobject resides in, and the object’s common name (if it has one) or a brief description ofthe object will be shown in the lower right. Move the telescope in the corresponding direc-tions shown by the guide arrows.
You can get more information about the selected object by pressing the Enter button.Thesecond line of the LCD display will then cycle information about the object you are view-ing such as its celestial coordinates (R.A. and Dec.), magnitude (brightness), size (in arc-minutes or arc-seconds), and a brief scrolling text description.
When you are finished viewing the selected IC object, you may scroll to another IC objectby using the arrow buttons, or you can select another IC object to view by pressing theIC button again.
6. Locating Deep Sky Objects byObject Type
Rather that trying to select objects by catalog numbers, you may wish to simply view cer-tain types of objects. This is where the Nebula, Galaxy, and Cluster buttons come inhandy. These buttons will access a selection of the best and brightest nebulas, galaxies,and star clusters in the night sky.
The Nebula, Cluster and Galaxy buttons are organized by constellation. So, beforeusing these buttons, decide in which constellation you would like to view an object.Choose a constellation that is at least 40˚ high in the sky to get a good view. If you areunsure of the constellations currently visible in your night sky, consult a planisphere orthe monthly star chart at telescope.com.
Locating NebulasAmongst the most beautiful objects in the night sky, nebulas are clouds of dust and gasthat are lit by a nearby stellar source. There are several different types of nebulas; emis-sion nebulas, which are where star systems form, planetary nebulas, which are the resultof a star dying, and reflection nebulas, which are caused by dust reflecting starlight. Mosthave low surface brightness, so a dark sky free of light-pollution is best for a night of view-ing nebulas.
To view a nebula, press the Nebula button on the controller. The LCD screen will thendisplay the word “NEBULA” with a flashing three-letter constellation designation after it.Now, select the constellation in which you would like to view a nebula. Use the arrow but-tons to scroll through the list of constellations. If you are unsure which constellation thethree-letter designation represents, refer to Appendix C. Once you have selected the con-stellation, press Enter. A nebula in that constellation will now appear on the LCD screen,along with the guide arrows to lead you to the nebula. The current constellation is shownin the lower left, and the nebula’s proper name or catalog number is in the lower right. Formore information about the nebula selected, press the Enter button.
To go to the next nebula in the selected constellation, simply press the up arrow button.The guide arrows will now direct you to the next nebula in the constellation. If there areno more nebulas available in that constellation, a nebula from the next constellation (in
14
alphabetical order) will be displayed. To select another constellation in which to view neb-ulas, press the Nebula button again.
Locating Star ClustersStar clusters are just what their name implies; groupings of stars. Star clusters come intwo main types, open and globular. Open star clusters reside within our Milky Way galaxyand usually contain a handful of stars clustered together because they were spawnedfrom the same gas cloud. Globular clusters are more like miniature galaxies, with hun-dreds or thousands of stars packed into a spherical shape by mutual gravity. Globularclusters reside outside the disk of the Milky Way galaxy and orbit the galaxy’s center. It isbelieved that globular clusters are formed as a natural consequence of galaxy formation.Star clusters, in general, are somewhat bright compared to other deep-sky objects, somany will appear quite spectacular, even in the smaller telescopes.
To view a star cluster, press the Cluster button on the controller. The LCD screen willthen display the word “STAR CLUSTER” with a flashing three-letter constellation desig-nation after it. Now, select the constellation in which you would like to view a star cluster.Use the arrow buttons to scroll through the list of constellations. If you are unsure whichconstellation the three- letter designation represents, refer to Appendix C. Once you haveselected the constellation, press Enter. A star cluster in that constellation will now appearon the LCD screen, along with the guide arrows to lead you to the star cluster. The cur-rent constellation is shown in the lower left, and the star cluster’s proper name or catalognumber is in the lower right. For more information about the star cluster selected, pressthe Enter button.
To go to the next star cluster in the selected constellation, simply press the up arrow but-ton. The guide arrows will now direct you to the next star cluster in the constellation. Ifthere are no more star clusters available in that constellation, a star cluster from the nextconstellation (in alphabetical order) will be displayed. To select another constellation inwhich to view a star cluster, press the Cluster button again.
Locating GalaxiesNebulas may be beautiful and star clusters impressive, but nothing has quite the breath-taking power of observing a galaxy. Galaxies are collections of billions of stars that comein a variety of shapes and sizes. Viewing a galaxy always gives the observer a revelationof just how vast our universe truly is. Keep in mind, however, that most galaxies are quitefaint, and may be challenging to identify, especially in smaller telescopes.
To view a galaxy, press the Galaxy button on the controller. The LCD screen will then dis-play the word “GALAXY” with a flashing three-letter constellation designation after it. Now,select the constellation in which you would like to view a galaxy. Use the arrow buttons toscroll through the list of constellations. If you are unsure which constellation the three-let-ter designation represents, refer to Appendix C. Once you have selected the constella-tion, press Enter. A galaxy in that constellation will now appear on the LCD screen, alongwith the guide arrows to lead you to the galaxy. The current constellation is shown in thelower left, and the galaxy’s proper name or catalog number is in the lower right. If youwish to have more information about the galaxy selected, press the Enter button.
To go to the next galaxy in the selected constellation, simply press the up arrow button.The guide arrows will now direct you to the next galaxy in the constellation. If there areno more galaxies available in that constellation, a galaxy from the next constellation (inalphabetical order) will be displayed. To select another constellation in which to viewgalaxy, press the Galaxy button again.

7. Locating StarsThe IntelliScope database contains 837 stars. Stars always appear like tiny points of light.Even powerful telescopes cannot magnify a star to appear as more than a point of light!You can, however, enjoy the different colors of the stars and locate many pretty doubleand multiple stars.You can also monitor variable stars from night to night to see how theirbrightness changes over time.
To view a star, press the Star button on the controller. The LCD screen will then displaythe word “STAR” with the word “NAMED” flashing next to it. From this screen, use thearrow buttons to choose from “NAMED,” “DOUBLE,” “VARIABLE,” and “CATALOG.”
Named StarsThe named stars are the brightest in the night sky. These are the stars that the ancientsgave proper names to, like “Arcturus” or “Mizar.”
To select a named star, press Enter after selecting “NAMED” from the Star button choic-es.You can now use the arrow buttons to scroll through the list of named stars. The starsare listed in alphabetical order. Once you have found the named star you would like toobserve, the guide arrows will direct you to move the telescope to the star’s position. Theupper left corner of the LCD screen will show the named star’s ST catalog number (theIntelliScope’s entire ST catalog is printed in Appendix D for easy reference), and thelower left shows the constellation in which the star resides. Pressing Enter again will dis-play the star’s R.A. and Dec. coordinates, its magnitude, and a brief description.
To find another named star to observe, simply continue scrolling through the list ofnamed stars.
Double (and Multiple) StarsMany stars in the night sky appear to be single stars, but they are not. They are actuallydouble or multiple star systems. Some of these systems comprise two or more stars grav-itationally bound to each other, while others are just two (or more) stars in the same lineof sight. At high magnifications, it is possible to “split” many double (and multiple) starsinto their individual components. It can also be interesting to contrast and compare thedifferent colors and magnitudes of the stars in the system. Be aware, however, that goodseeing conditions are critical for separating close components of a double or multiple star.
To select a double (or multiple) star to observe, press Enter after selecting “DOUBLE”from the Star button choices. The LCD screen will then display the word “DOUBLE” witha flashing three- letter constellation designation after it. Now, select the constellation inwhich you would like to view a double star. Use the arrow buttons to scroll through the listof constellations. If you are unsure which constellation the three-letter designation repre-sents, refer to Appendix C. Once you have selected the constellation, press Enter. A dou-ble star in that constellation will now appear on the LCD screen, along with the guidearrows to lead you to the double star. The current constellation is shown in the lower left,and the double star’s name is in the lower right.
Note: Double stars typically have names like “Zeta” (Greek letter designation) or a num-ber like “36” (Flamsteed number). The full names for these double stars are actuallylinked to the constellation they reside in. For example, in the constellation Andromeda,these stars would be “Zeta And” and “36 And.”
For more information about the double star selected, press the Enter button. (The “S=”now refers to the separation, in arc-seconds, between the double stars. For multiple stars,
16
the “S=” refers to the separation between the two brightest stars. The “M=” now refers tothe magnitude of the brightest star.) To go to the next double star in the selected con-stellation, simply press the up arrow button. The guide arrows will now direct you to thenext double star in the constellation. If there are no more double stars available in thatconstellation, a double star from the next constellation (in alphabetical order) will be dis-played. To select another constellation in which to view a double star, press the Star but-ton, select “DOUBLE”, and press Enter.
Variable StarsVariable stars are stars that change their brightness, also called magnitude, over time.The period of brightness change varies greatly from star to star; some variable starschange brightness over several days while others may take several months to noticeablychange. It is fun and challenging to watch a star’s magnitude change over time.Observers typically compare the current brightness of the variable star to other starsaround it (whose magnitudes are known and do not change over time).
To select a variable star to observe, press Enter after selecting “VARIABLE” from theStar button choices. The LCD screen will then display the word “VARIABLE” with a flash-ing three-letter constellation designation after it. Now, select the constellation in which youwould like to view a variable star. Use the arrow buttons to scroll through the list of con-stellations. If you are unsure which constellation the three-letter designation represents,refer to Appendix C. Once you have selected the constellation, press Enter. A variable starin that constellation will now appear on the LCD screen, along with the guide arrows tolead you to the variable star. The current constellation is shown in the lower left, and thevariable star’s name is in the lower right.
Note: Variable stars typically have names like “Eta” (Greek letter designation) or a letterdesignation like “R.” The full names for these variable stars are actually linked to the con-stellation they reside in. For example, in the constellation Aquila, these stars would be“Eta Aql” and “R Aql.”
For more information about the variable star selected, press the Enter button. (The “M=”refers to the mean magnitude of the variable star.) To go to the next variable star in theselected constellation, simply press the up arrow button. The guide arrows will now directyou to the next variable star in the constellation. If there are no more variable stars avail-able in that constellation, a variable star from the next constellation (in alphabetical order)will be displayed. To select another constellation in which to view a variable star, pressthe Star button, select “VARIABLE,” and press Enter.
Catalog (ST) StarsThe “ST” catalog contains all of the stars in the IntelliScope Computerized ObjectLocator’s database. This catalog has 837 of the most interesting stars to view in the nightsky. The full list of stars appearing in the ST catalog is printed Appendix D. Generally, thebest way to use the ST catalog to observe stars is first to peruse Appendix D, and thennote the catalog number of the star you wish to observe.
To select an ST catalog star to observe, press Enter after selecting “CATALOG” from theStar button choices. The LCD screen will then display the letter “ST” with three digitsblinking after it. Now, input the ST catalog number of the star you wish to observe, andpress Enter. If the ST catalog number of the star you wish to view contains three digits,it is not necessary to press Enter after inputting the third digit.
17
The object’s ST catalog designation will be shown in the upper left corner of the LCDscreen, with the guide arrows in the upper right. The lower left will show the constellationthe object resides in and the star’s name.
You can get more information on the star selected by pressing the Enter button.The secondline of the LCD screen will then cycle information about the object you are viewing, such asits celestial coordinates (R.A. and Dec.), magnitude (brightness), and a brief description.
When you are finished viewing the selected star, you may scroll to another star in the STcatalog by using the arrow buttons, or you can select another ST catalog star to view bypressing the Star button, and pressing Enter once “CATALOG” is selected.
8. Tours of the Best ObjectsThe IntelliScope controller offers guided tours of the best and brightest celestial objectsvisible in the sky each month. There are 12 monthly tours, each consisting of 12 pre-selected objects.The tours are an easy and fun way to locate and observe the finest won-ders of the heavens. They are a great place to start for a beginner who is unfamiliar withthe night sky, or for a more experienced observer who wants to revisit some old favoritesor show friends or family “what’s up” on a given evening.
Starting a TourTo start an IntelliScope tour, press the Tour button at any time after you have aligned theIntelliScope system. The LCD screen will display “SKY TOUR” and a flashing three-letterdesignation for the month. Scroll through the months by using the arrow buttons until youreach the present month, then press the Enter button.
The LCD screen will then display the first tour object for the selected month in the lowerright of the screen, with the guide arrows in the upper right. Use the guide arrows topoint the telescope, and you will soon be observing the first astronomical showpiece ofthe month.
You can get more information about the current tour object by pressing the Enter button.The second line of the LCD screen will then cycle the following information about theobject you are viewing: its celestial co-ordinates (R.A. and Dec.), magnitude (brightness),size (in arc minutes or seconds), and a brief text description.
When you have finished viewing the first tour object for the selected month, you can con-tinue the tour by pressing the up arrow button to find the next object.You can exit the tourat any time by pressing any one of the other function buttons on the controller.
Since several months’ tour objects are visible in the night sky at one time, feel free toselect a month before or after the current month. These tour objects will likely be visiblealso. Remember, however, that viewing objects below 40˚ or so from the horizon will notgive the best view due to atmospheric distortion (and usually light pollution). If you arefinding that objects in the selected tour month are too close to the horizon, you shouldchoose a month following the selected month, or you can wait a few hours for the objectsto rise higher in the sky!
9. The Identify FunctionThere may come a time in your observations when you spot an unidentified deep-skyobject or star in the eyepiece and want to know what it is. With the IntelliScopeComputerized Object Locator, a simple press of a button will tell you.
18
Using the ID ButtonWhen you locate an object and center it in the eyepiece, you can identify it by simplypressing the ID button. The LCD screen will display “IDENTIFY” with the word “ANY”flashing. You can then use the up/and down arrow buttons to scroll through several morespecific options (“STAR”, “DOUBLE”, “CLUSTER”, “NEBULA”, and “GALAXY”). If youknow which one of these object types you are looking at, selecting the object type willmake the identification quicker and more accurate. This is because the computer willsearch through a shorter list of potential object matches, and will allow proper identifica-tion if there are several objects within the same field of view. If you are unsure of theobject type you are looking at, simply select “ANY” from the list of choices. Once you haveselected the object type (or “ANY”), press the Enter button.
The identity of the object centered in the eyepiece will now be displayed in the lower rightarea of the LCD screen. The constellation in which the object resides is shown in thelower left. As always, to get more information about the object, press the Enter button.
An interesting feature of the ID function is that once initiated, it is continually active. So,if you press the ID button, and choose “STAR”, for instance, you can move your telescopefrom star to star in the sky, and the controller will automatically display the star’s identitywhen you center the star in the eyepiece. This can be a fun and easy way to identify thestars in the sky. In fact, you can even make a “Name That Star” game out of it! Point yourfinger at a bright star in the sky and see if you can name it. Then, just point the telescopeat the star to see if you were correct or not. If the centered star is not in the controller’sdatabase, it will display the identity of the closest star that is in its database.
To exit the identify function, simply press any other of the controller’s function buttons. Ifyou would like to identify another object type, press the ID button again.
10. Adding User-Defined ObjectsNot only does the IntelliScope’s database contain over 14,000 fascinating objects to view,you can even add your own! Up to 99 user-defined objects can be entered into the data-base by means of the User button. These user-defined objects can be random stars, afaint object not contained in the controller’s database, or just a pretty object that youwould like to come back to at some point in the future.
To enter a user-defined object into the database, you must have the right ascension (R.A.)and declination (Dec.) coordinates for the object. If you are currently observing an objectthat is not in the controller’s database and you wish to add it, but don’t know its coordi-nates, you can use the FCN button to obtain its coordinates (described in next section).
To input a user-defined object, begin by pressing the User button. The LCD screen willdisplay the word “NEW” with a two-digit number flashing after it. Since no user-definedobjects currently exist, press Enter to create user-defined (“NEW”) object number 01.The LCD will display the R.A. and Dec. coordinates for the “NEW” object selected in thelower left. Since no data has been input yet, these coordinates will be 00:00 +00.0. Thefirst four digits indicate the R.A. coordinate (in R.A. hours and minutes), and the remain-ing digits (and the ± sign) indicate the Dec. coordinate (in degrees). Now, press the Enterbutton, and the first two digits of the R.A. coordinate (R.A. hours) will begin flashing.Press the two numerical buttons on the keypad that correspond the hours value of theR.A. coordinate. If the value of the R.A. hours is less than 10, make sure to enter a zerofirst. Then the second two digits of the R.A. coordinate (R.A. minutes) will begin flashing.Press the two numerical buttons that correspond to the minutes value of the R.A. coordi-nate. If the R.A. minutes are less than 10, make sure to enter a zero first. Next, the sign
19
of the Dec. coordinate will be flashing. Use the arrow buttons to select “+” or “-”for theDec. coordinate. Then, the first two digits of the Dec. coordinate will begin flashing. Pressthe two numerical buttons that correspond to the degrees value of the Dec. coordinate.Then the tenth of a degree value for the Dec coordinate will begin flashing. Press thenumerical button that corresponds to the tenths of a degree value for the Dec. coordinate.
You have now input the data for your first user-defined object. Remember that this objectis now “NEW01”. If you wish to view this object in the future, press the User button, andpress Enter once “NEW01” is selected. The guide arrows will then tell you where to pointyour telescope to find the user-defined object.
If you wish to input another user-defined object, select “NEW02” (by using numerical but-tons or the arrow buttons) after pressing the User button and input the data as outlinedpreviously. If you select a “NEW” object number that you have already entered coordi-nates for and attempt to input new data, you will lose the data that was input previously.You may find it convenient to keep a written log of the “NEW” objects so that you can eas-ily keep track of them.
11. The FCN ButtonThe IntelliScope Computerized Object Locator has several other useful functions, a cou-ple of which can be accessed by using the FCN (function) button.
R.A. and Dec. CoordinatesBy simply pressing the FCN button, the controller will give a continuous readout of thetelescope’s current R.A. and Dec. coordinates. This can be helpful and powerful in anumber of ways. You can easily find any object in the night sky if you know its rightascension and declination coordinates. Grab any star atlas, choose any object you wishto view, be it faint galaxy or random star, and jot down its coordinates. Then, once youhave aligned the IntelliScope system, you can point the telescope to that location bysimply pressing the FCN button and moving the telescope until the R.A. and Dec. coor-dinates displayed match the coordinates of the object you wish to view. You can alsopress the FCN button at any time to display the current R.A. and Dec. coordinates ofwhatever you are currently viewing.
A common use for the FCN button is to locate “transient” objects, such as comets andasteroids. To find these objects you will need to learn their coordinates from astronomyresources, such as Astronomy, Sky & Telescope or a reliable astronomy website. Cometand asteroid positions will change from night to night, so entering the current coordinatesinto the user-defined database is generally not useful.
After pressing the FCN button, the R.A. and Dec. coordinates corresponding to the cen-ter of the telescope’s field of view are displayed on the first line of the LCD screen. Thelower left of the screen indicates the current constellation the telescope is pointing to. Thelower right numbers are the current azimuth (“AZ”) and altitude (“ALT”) coordinates of thetelescope; this information is generally not useful.
The Realignment FunctionThis function is useful for obtaining a new alignment fix during an observing session tocorrect for small pointing errors. Use this function only when pointing accuracy for a cer-tain area of the sky appears to be poor compared to other areas of the sky. This is evi-dent when objects in one area of the sky consistently fall at the edge or just outside thefield of view (of the 25mm eyepiece) when the numbers on the LCD screen read 0.0 0.0.
20
This can happen if the alignment stars initially chosen during setup are somewhat closeto each other (less than 60˚ apart) or if the area of sky being viewed is a considerabledistance away from the alignment stars chosen.
To improve pointing accuracy in a specific area of the sky, select an object in the locator’sdatabase from that region, and use the guide arrows to find the object. Precisely centerthe object in the eyepiece (preferably a high-powered one). Now, press the FCN button,and the R.A. and Dec. coordinates of the centered object will be displayed. Then, pressthe Enter button.The LCD screen will now display “ALIGN OBJECT 3” on the first line, andwill be flashing the object currently centered in the telescope on the second line. PressingEnter again then realigns the IntelliScope system to the object centered in the telescope.The LCD screen will display a new “warp factor” associated with the new alignment. If thisnumber is greater than ±0.5, you may want to consider resetting the controller to performanother two-star alignment. Turn the controller off, then on again (with the Power button),to do this.
If, instead of pressing Enter a second time after pressing the FCN button, you press oneof the arrow buttons, the list of initial setup alignment stars will be displayed. If you wish,you can select one of these alignment stars to realign on. Do this by scrolling to thedesired alignment star using the arrow buttons, center the star in the telescope, andpress Enter.
In general, it will not be necessary to use the realignment function, but it is a handy fea-ture to have at your disposal. Also, be aware that while pointing accuracy will increase inthe area of sky around the object realigned on, it may decrease in other areas of the sky.
12. The “Hidden” FunctionsAll of the active functions of the IntelliScope Computerized Object Locator have been out-lined. There are, however, some additional “hidden” functions that may be of some use toyou. To access the hidden functions, press the Enter button while pressing the Powerbutton to turn the controller on. The LCD will display its introduction screen (with softwareversion number) and then show the words “ALT AZM TEST.” This is the first hidden func-tion. Scroll to the other hidden functions by using the arrow buttons. The other hiddenfunctions are “ENCODER TEST,” “DOWNLOAD,” “CHECKSUM,” “REWRITE,” and“CLOCK.” When the hidden function you wish to use is displayed, press Enter to selectit. To exit the currently chosen hidden function, press any button except for the Enter orarrow buttons. To completely exit the hidden functions section of the controller, you willneed to hold the Power button down until the controller turns off.
The rest of this section gives the details and purpose of each hidden function.
Altitude and Azimuth TestThe altitude and azimuth test (“ALT AZM TEST”) is a diagnostic test that gives relativealtitude and azimuth positions for the telescope. This test will allow you to easily see if theencoders are “talking” to the controller, and if the encoders are accurately monitoring thetelescope’s motions. To effectively use this test, make sure the telescope optical tube isin the horizontal position when pressing the Enter and Power buttons to access the hid-den functions.
Once “ALT AZM TEST” is chosen from the hidden function options, the LCD screen willdisplay the telescope’s current relative altitude and azimuth position (in degrees); the rel-ative altitude is in the upper right, while the relative azimuth is in the lower right. To begin
21
with, both of these numbers will be +000.0. The first two sets of numbers on the upperand lower lines of the LCD screen are meaningless for the purposes of this test.
If you move the telescope counter-clockwise in azimuth, the number in the lower rightshould increase, while if you move clockwise in azimuth, the number will decrease. If yourotate the telescope exactly 360˚ in azimuth, the readout should return to the original+000.0 reading.
If you move the telescope upwards in altitude, the number in the upper right shouldincrease, while if you move downwards in altitude, the number will decrease. If the tele-scope tube was perfectly horizontal when you enabled the hidden functions of the con-troller, then the altitude will read +090.0 when the telescope is pointed precisely vertical.
If one, or both, of the encoders are not behaving properly when performing this diag-nostic test, there may be a problem with the assembly of the system, or a problem withone of the encoder boards or discs. Also, be sure to check that all cable connectionsare secure.
Encoder TestThe encoder test is another diagnostic test that gives information about the performanceof the encoders themselves. Select “ENCODER TEST” from the list of hidden functionsusing the arrow buttons and press Enter.
The LCD screen will now display two lines of data. The top line of data corresponds tothe altitude encoder, while the lower line of data corresponds to the azimuth encoder. Thefirst two digits on each line denote the amplitude of the signal from one of the magneticsensors on the encoder board, the second two digits represent the amplitude from theother sensor on the encoder board. The numbers are in hexadecimal (base 16) digits.Therefore “A” in hexadecimal represents “11” in decimal, “B” represents “12” in decimal,“C” represents “13,” “D” represents “14,” “E” represents “15,” and “F” represents “16.” Whenmoving the telescope in altitude or azimuth, you will note that each of the digit pairs risesand falls. None of the digit pairs should ever go above “F3.” If they do, then the encoderdisk is too close to the sensors on the encoder board. This will generally not happen inaltitude, but can happen in azimuth.
If you notice that the first or second digit pair on the second line of the display goes above“F3,” then try loosening the lock nut on the azimuth nut of the base by about 1/16 turn. Ifthis does not work, you will need to disassemble the azimuth encoder (azimuth encoderdisk, brass bushing, and azimuth encoder board) and reassemble it carefully accordingto the instructions that came with the IntelliScope Dobsonian telescope itself.
If you notice that the two digit pairs on the first line are going above “F3,” then there is aproblem with your altitude encoder assembly. More than likely, the altitude encoder diskis bent.
The three-digit number displayed after the digit pairs on each line is the “radius” for eachencoder. This number should not go above about 125 or below about 30. If it does, per-formance may be compromised for the corresponding encoder. If the number goes above125, then the encoder disk and magnet may be too close to each other. If the numbergoes below 30, then the encoder disk and magnet may be too far away from each other.Also, if the radius varies by more than 30 counts in a cycle, encoder performance maynot be optimal, and you should contact Orion’s Customer Service Department.
The four-digit number at the end of each line is the raw encoder “ticks” in hexadecimalnumbers. This information will generally not be useful for diagnostic testing of theencoders.

DownloadThis function allows downloading of software changes and upgrades available fromOrion’s website. To use this option, you must have the optional IntelliScope-to-PC cable,available from Orion. Check www.telescope.com for more information about availablesoftware downloads for the IntelliScope Computerized Object Locator.
ChecksumThe checksum function is used to make sure that software has loaded into the controllerproperly. It has no purpose until a new software version is downloaded. Check theIntelliScope download section on www.telescope.com to see what the proper checksumshould be for each new software version.
RewriteRewrite is also only used after a new software version has been downloaded. It rewritesthe new software into its memory in order to prevent any potential problems from arisingafter the software transfer.
ClockThis function allows use of the IntelliScope system with equatorial platforms forDobsonian telescopes. If you are using your IntelliScope with a Dobsonian equatorialplatform, press Enter when the selection “CLOCK” is displayed from the available “hid-den” function choices. The LCD screen will then show the word “ON” blinking. For normaloperation of the IntelliScope system, the controller’s internal clock should be on. For usewith a Dobsonian equatorial platform, use the up or down arrow button to change “ON”to “OFF,” and press Enter. The controller is now ready to be used with a Dobsonian equa-torial platform. Now, when you press Power to turn the controller on, the LCD screen willstate “CLOCK IS OFF” on the second line of its introduction screen.
To turn the controller’s internal clock back on, access the hidden functions, select“CLOCK,” press Enter, change the “OFF” back to “ON,” and press Enter again.

should be tightened 3/16 to 1/4 turn past when the fender washer is no longer looseunder the nut.
2. Does the brass bushing extend slightly above the top surface of the top baseplate? Ifnot, the bushing or top baseplate may need replacement, or there may be an assem-bly problem.
3. Is the azimuth encoder disk (magnet) bent? If so, you will need to flatten it by bend-ing.
4. Is the azimuth encoder board trimmed flush on the side in contact with the top base-plate? If not, the board will not seat flat against the baseplate and this may cause theencoder’s sensors to come too close to the encoder disk.
5. Is the brass bushing properly registered with the azimuth encoder disk? The featureon the front of the bushing needs to seat into the hole in the disk.
Altitude encoder, in general6. Is the altitude encoder disk significantly bent? If so, the altitude encoder assembly will
need replacement. Also, if the altitude encoder mounting screws are loose, there isan increased chance of the user bending the altitude encoder disk.

Warp factor consistently above ±0.5 but below ±2.07. Check accuracy of vertical stop. Use a carpenter’s level to do this.
8. Are alignment stars being centered with reasonable precision? A high-power eye-piece (at least 10mm focal length), or an illuminated reticle eyepiece (preferred) isrecommended.
9. Check encoders as outlined previously.
10. Try to use alignment stars that are well above the horizon. Light from stars is refract-ed as it travels through the atmosphere and starlight near the horizon has to travelthrough the greatest amount of atmosphere before reaching your telescope. Starsnear the horizon can appear as much as 2° away from their actual position.
11. Avoid long delays between aligning on the first and second alignment stars. The starsin the night sky appear to move due to the rotation of the Earth. If you take more thana few minutes to align on the second star, this stellar motion will result in an increasein the warp factor (and decrease the resultant pointing accuracy). This is because thecontroller does not yet have a frame of reference to tell which way the stars shouldappear to be moving before the second star is aligned on.
Warp numbers larger than 2.012. Are the stars you aligned on actually the stars you select-ed on the controller?
Consult the finder charts in Appendix A if you are unsure.
13. The encoder sensors may be coming into contact with the encoder disks. Check boththe altitude and azimuth encoders as outlined above.
Altitude readouts do not change when you move the scope (during “ALT AZM TEST”)14. Check the altitude cable’s connections.
15. Make sure the knob that goes through the altitude encoder is tight.
Azimuth readouts do not change when you move the scope (during “ALT AZM TEST”)16. Check the azimuth cable’s connections.
17. Make sure the hex lock nut on the azimuth axis screw is tight. The fender washerunderneath the hex lock nut should not be able to move. Remember, the hex lock nutshould be tightened about 3/16 to 1/4 turn beyond the point where the washer can-not move any longer.
18. Try disassembling then reassembling the azimuth encoder by disassembling the topand bottom groundboards of the base.
If you need to contact Orion Technical Support, email [email protected] or call(800) 676-1343.
