@Tony, does it mean that if i take 10x20second avi movies during a period of an hour for example, i can still stack all of them ?

Pretty sure i read somewhere that you can't take an AVI of Jupiter longer than 90 seconds somewhere

I am no expert by any means, but the cool images that Quark, Bird, Iceman and others produce are captured in RGB, 3 separate captures for each channel. I can't remember the details of their captures but I'll make a few assumptions, hopefully on the conservative side.

Probably capture at 30 fps for at least a minute for each channel. Between each capture they have to stop capture, change filter, resume capture. Each of their composite shots may have taken 5 minutes? In that time Jupiter will have moved and as a result the trailing and leading edges display the colour variation from features appearing/disappearing between channels.

Capturing over an hour is a big ask, as Jupiter will have rotated substantially in that time. You should be able to take a number of sequences... would you pause the capture, or are you able to join the captures? You should be able to do a few sequences, process them and stack the resulting images... just don't take them too far apart is my guess.
