Yeah I have the USB traffic to the max and also high speed ticked on. I use 16bit although it's slightly slower on recommendations from Anthony (bird) who leaves it on all the time. It has a better dynamic range and there are many instances when you need the extra signal. I lose may be 10fps on it in worst case scenario. I guess it's all a compromise.

I agree. The more the better. The stack difference between 4000 and 10000 definitely starts showing during processing and how much details you can get out and sharpen.

Mate, any tighter and it will be tighter than a fish's ass. I have just enough black around the disc to keep the wobble within the FOV. I think the 120MM USB2.0 is an old camera. Maybe down the road if I get serious about planetary I'll get one of those flea cameras. Nearly bought one from the classified years ago. I should have.

For Saturn I use 5 minutes at 100 fps (so 30000 frames total) at 37 gain, and stack 5000 to 10000 frames.
100fps on Saturn. That's my wet dream. Oh well, for now I'll do with what I have
