This is a series of shots I did of Jupiter and the GRS rotating around to the back. 1980 C-8 Toucam 740k, Meade 2x barlow on f20 shots. First shot is at f10, the remainder are at f20. Seeing was only so-so. Had to contend with fireworks and mosquitos!
your pictures are difficult to see as they are too dark and much of the planet disappears (only in the F20 shot posted at 10:40 PM I can see the whole planet). You may want to increase brightness in you images and if that doesn't do it, then I'm afraid you have to tweak your capturing parameters in order to record a brighter image.
