Re: jupiter problem
Its an 80s exposure. I would think that satellite is moving much faster than Jupiter is rotating?

will it be due to moving too fast? it shall not be the case.
it shall be any big issue, if with in 120s for shooting Jupiter
i guess it could relate with Optical Axis. any one come cross this issue before?
Re: jupiter problem
It could be an artifact from stacking. If you are experiencing excessive movements from frame to frame, stacking registration may focused on the main globe while missed out on the outer regions. Try stacking with fewer frames and see if this will go away.
