Hongkong Double Star Observations. (Continued from A. N. 3378).
By W: Doberck.
The following observations were made with the Lee Equatoreal, which is upwards of eighty years of age, and nearly past use. It is placed in the open air, and is very unsteady, especially when there is a breeze blowing. The clock works comparatively well, and is in fact still superior to the driving clock I used at Markree. The stars are kept near the centre of the field by a Dawes' slide. A drawback is the complicated eye-end of the telescope. The position circle is divided on the rim, so that in certain positions of the telescope the observer has to rise and walk round to read it. The divisions go in the wrong direction. There are two screws, with divided heads, placed on opposite sides of the eyepiece, each of which carries a wire. It is better to have only one moveable wire. Then the coinci- dence of the wires would be constant, but good micrometer screws have no sensible errors, and to obviate the danger of wearing the screw in course of time, several groves, half a revolution apart, for fixing spider lines, may be ruled on the sliding part and used alternately, when the wires are renewed. Such an arrangement might with advantage be adopted also in case of meridian circles. To make the fixed wire moveable by half a revolution is most objectionable. The ocular itself is moved across the field by aid of a screw fixed in front and with its axis perpendicular to the micrometer screws, which is the proper arrangement. There are no means of reading off whole revolutions except by aid of a comb, which is visible only with lower powers than those used on double stars. Such circumstances make the observer liable to commit such mistakes as are found in some of Admiral Smyth's observations. I have therefore checked my observations by comparison with previous records.
I observed a coincidence of the wires in four different positions of the head of the screw. Taking differences from the mean I obtained with head up +0!'09, with head down -0107, with head to the right -1-01'09, and to the left -o!'I I . These figures are somewhat similar to those ob- tained in Copenhagen (A. N. 3680), and are evidently due to personal equation.
The changing of the magnifying power is most con- venient, as all the oculars used on double stars fit the same adapter. In some of the latest telescopes this convenience does not exist, and one has to screw on and off eyepieces the whole time. I always use the highest power available and which the steadiness allows of. With this six inch, or rather 53/4 inch, it was 600. The difficulty in using such a
88
Bad definition not only increases accidental, but more especially does it cause and increase constant errors. Should the definition momentarily improve, then the angle and di- stance is seen to be different from that noted under poor definition. A proposal to utilize this circumstance for the investigation of upper wind direction does not look pro- mising, but it explains one of the reasons why double star observations ought to be scattered over a large portion of the season, so as to make them, as far as possible, inde- pendent of each other.

Many of the objects have been selected from Mr. Innes' list of southern double stars, but I prefer to give the initials and numbers of the discoverer, which has certain advantages, General catalogues are most useful, but it is to be hoped, that the practice of referring to stellar objects by their numbers in such catalogues will become obsolete, and that stars discovered by Burnham, Hough, and others, will con- tinue to be known under their present designations. It is to be regretted that Herschel's double stars are so often
1 denoted by numbers in Struve's list.
