Strange happenings with Jupiter on Saturday
It finally cleared on Saturday night so I thought I'd give Jupiter a shot. It was early in the night (around 11:00 to 12:30ish) so the seeing was moderate to poor. I saw Io popping out from behind Jupiter and decided to try to catch it on video. I had the saturation and gain set fairly high so the images are very yellowy-green. Strange thing though is that all exept 1 of the videos when processed end up with checkerboard patterns over them. (See second set of images) The right one in the first set here had it as well but I managed to remove nearly all of it.
Can anyone explain why this might have happened. Unfortunately as it was a spur of the moment decision, I didn't write down the settings I used. I used K3CCD to capture, WcCtrl to adjust settings, Registax 3 to stack and Photoshop for final adjustments. The checkerboard was there after waveletting in Reg3. I do remember that I'd set the gamma around 10 - 15 and the fps were fairly high I think ( more than 25fps). Would either of these cause this effect?
