The camera, including temperature settings, appears to be functioning properly again. Thanks for the update.

By the way, if you need to do any live debugging against an SV605CC or SV305PRO, my laptop setup is at your disposal, I'd be happy to set up remote access to aid however might be needed.

I understand, my description was a bit vague. It's partly because I couldn't fully explain it myself. Pictures would come out super dim and grainy and then randomly look right, and then back to dim and grainy. I wasn't able to identify any kind of pattern to it. I did save a few FITS of the dim grainy images, but I neglected to re-take new images with the same settings once I had corrected it. I could upload those, but it would probably be better for me to just wait until tomorrow night (next clear night) and generate new images with consistent settings before and after applying the latest commit. I'll be back Saturday with more info.

I'll try to rig up a test this evening. If the gain issue does re-occur, what kind of informational can I gather to help troubleshoot?

I read the code change, I saw the change to temperature handling. Last Tuesday was the first time I decided to try using the cooler, and was confused that it couldn't get as cold as it was supposed to and I thought my equipment might be defective, that change explains it exactly. Thanks for taking care of that.

I'm experiencing issues with the new driver as well, with my SV605CC. I haven't been able to establish the exact pattern, but after reading this thread I think it is related to the issues setting gain. Basically my images are only sometimes coming out with any gain applied, at least that's how it appears.

I checked out the commit before the reimplementation, and everything's working as expected again. The issue is occurring very consistently, so if there's any testing I can do let me know. I did test with the current master commit, it exhibited the same gain-less behavior.
