After a promising first go at imaging I was keen to try again.
Friday night just after midnight promised a GRS with ganymede transit, so even though there were enough clouds out to prevent sky-sense from auto-aligning, I could still see jupiter and saturn by eye (but nothing else really) I tried again.
This time (thanks to some good feedback and advice here) I found the uncompressed Y800 format, and took longer videos. FPS was still lowish, because I needed 1/30sec exposures even with 2x binning and max gain.
Despite the much worse conditions, I think I can see definite improvement.
Really wanted the red spot further round, and that shadow of ganymede more in the picture ... but the thick clouds had other plans.
