Fantastic image, Mike. The detail on Ganymede is really spectacular. I'm looking forward to the videos. Hey, where are all the images from the East Coast on Jan 4? I figured everyone would be out that night, but I've only seen a few images here and on the Alpo list.
Pete - you can also do the long video technique. I derotate 5 minute SERs in WinJupos. The derotation takes a long time, but I think the results are worth it. Plus it makes it possible to let Firecapture image all night while I sleep. I take one RGB set every 20-30 minutes.
Thanks Kevin, yes I have de-rotated video files up to 7 minutes long; I was just wondering if there was a limit on how long the file can be because the best amateur imagers like Damian seem to stop at about 9 minutes.
I did image Jupiter on Jan 4 from Maryland about 50 miles northeast of you but it was only 9 degrees F so I opted to do it from my balcony with the planet at only 38 degrees elevation; that was a big mistake because Jupiter was over a 4 story apartment building that was emitting lots of heat in the super cold night air. I think that's why the seeing was so erratic even though above average seeing was predicted. The results were less than inspirational.
