Took this last night with my Canon 300D and XT6. Jupiter is a stack of 80+ shots and is pasted onto an overexposed shot that brings out the moons.
I am still working on trying to bring out more details on Jupiter. When I am stacking pics using Registax, should I lean toward (shorter exposure, high ISO 400-1600) or (longer exp, low ISO 100-200) The big issue is that without having the ability to track Jupiter it is flying across the frame so I cannot do too long of an exposure without blurring just from apparent motion.

Excellent, especially considering that you have no tracking!
Generally, the lower the ISO, the lower the noise.
Are you using the continuous mode of your Rebel?

Thanks for the comments!
I made a shutter control box out of an old Motorola pager body, stereo cable and 3 switches. I then set the scope up so that Jupiter starts at one side of the frame and as it moves across I snap pictures. With the near instantaneous response of the 300D I can wait for the best viewing (it was a little windy when I took these shots) before taking the shots. I can usually take 6-10 shots before having to move the scope. How many shots can I take before field rotation starts to impact image stacking using RegiStax?

IT is usually based upon time, and I think that I have read it is somewhere in the 3 to 5 minute range.
BTW, while I am sure that it will make it much harder(maybe impossible!) for you, tracking wise, you may want to think about a barlow.
