Frames of your video

• Your video is divided into many individual frames

• Most planetary imaging requires several hundred, perhaps around 200-400

• More frames don’t always mean a better image

Click Select,Find a video file

Reference image

• A reference frame is what you decide to be the best looking image in your video

• Using the frame slider at the bottom, choose a frame you feel is one of the best images

First step: Alignment

• Alignment must be done because your video file always shows some wobble or interference due to:– Wind blowing against the telescope– Birds or airplanes flying over head– Accidental touching or bumping the telescope

• Clicking the left mouse button on the image displays a little red dot, this is an alignment point

Alignment points

• Alignment points are used to align all the images based on your chosen reference image

• Registax can do this automatically, or you can do it manually, depending on how large the planet appears in your video

• Small planet images may require you to set your own alignment points

Goal of alignment points

• You want:– Several but not an insane amount of them– To stay away from the edges of very bright and

very dark areas– Be inside the planet / object, not around it– Large planets, around 20-30– Small planets you might only have 5-10

Set Alignment points, then click ALIGN

Limit the number of frames

• You will never use ALL of your frames, you don’t want to

• You only want the best of the best frames• You must limit the amount in the limit setting
