I've used Astro IIDC for years now for planetary imaging but I thought it was time to do a comparison study. To do this I needed to convert the captured QT movie to an .avi movie. I wasn't able to figure out how to create an uncompressed avi movie from an uncompressed qt movie. So I just used the highest bitrate possible which created a 20 MB divx .avi file from a 350 MB Astro IIDC encoded QT movie. You can see the results side by side in the attached photo.Despite a lot of fiddling with parameters in Registax I could not get anymore detail from Registax. I will admit the ASTRO IIDC image is somewhat oversharpened to enhance detail. This is the same image posted yesterday.

However Registax has a "dering filter" which proved desirable. When properly adjusted it smoothes the hard planetary edge to give a more realistic 3D appearance to Jupiter. I don't know if that is really its intended use but I like the effect. Astro IIDC always gives a flat appearance to Jupiter as if it was a coin.
