Jupiter rotation animation
Jupiter, I shot this a wee while ago.. 2010 October 6-7
An animation of about 1/3 of Jupiter's rotation, captured using a 25cm Newtonian telescope at f5.6 and a Philips SPC900NC, using wxAstrocapture to control the webcam and record the videos to disc. A new video was shot every 10 minutes over three hours.
Registax was used to process each video. About 500 video frames (each 1/100s exposure) were averaged (stacked) for each frame of the final animation.
Registax was also used for the final registration of the frames for the animation, then Imagemagick to make the final animated GIF you see here (by clicking on the original-size option). Non "pro" flickr users can see the animation here: dl.dropbox.com/u/11530205/jupiter_rot.gif
It is not really very good, but serves of an example of what you can achieve using basic equipment and the wonderful software tools freely available.
