JUPITER MOVIE (25 Sep 2010)
The moon Ganymede crosses Jupiter on 25 Sep 2010.
Ganymede is pretty big and so is its shadow...

We used a Meade LX-200 10" f/10 telescope and a 2x Barlow lens.
We used HandyAvi and a ToUcam webcam to create a 500 frame AVI movie every 5 minutes.
Each AVI file was then processed using RegiStax to produce each single JPG frame of the movie.
HandyAvi was then used to create the movie from the JPG images.
The images degraded as Jupiter sunk toward the horizon.
We used a Temperature-Compensated Focuser to maintain focus of the telescope throughout the night.Everything was automated.
We used HandyAvi to automatically keep Jupiter centered in the telescope and to automatically take 500 frames every 5 minutes. We set it up then went to bed... :-)
