Thanks Dave. We've been so used to shooting Jupiter high in the sky during our cooler months that I'd forgotten the challenges shooting it low in the north in warmer temperatures. My thought was that if I ran it at a higher Gain such as 300 or so to get a higher frame rate and reduce exposure, noise with a sensor running at 31.5 degrees celsius, would have been horrendous. I chose to sacrifice frame rate for a smoother result and combine the best 10% of several 90 second video grabs to achieve this. I also shot these at 640 x 480 ROI to reduce data size and increase frame rate but that didn't make much difference, exposure was 100000 us. It was just a theory, really don't know if it helped much.
