Thanks for the answers. The Nexstar 4SE (which is a MAK) will have a much lower light gathering power than my C8 (which is an SCT and larger aperture), hence your higher exposure (and lower frame rate). A comparison of the 4SE and 8SE (similar to the C8 SCT):https://www.bhphotovideo.com/c/compare/ ... 440825-REG
The light gathering power (compared to the human eye) of the 4SE is 212x, for the 8SE is it 843x.
I think you would be best to practise Jupiter capture using the exposure of 30ms which has given you a frame rate of around 30fps. These were 18_58_36.cameraSettings: SER, RAW8, 640x480, gain=383 and brightness=0. I might be beneficial to drop the gain to around 300. The image quality will depend on atmospheric conditions. A 60s capture should give you just under 2000 frames, try stacking the best 30%.
Good luck.
