Hi,

Maybe this doesn't help here - with QHY174GPS, SC 3.3.7093.0, QHY driver from Feb. 2020: no problems with cooling.

Cheers, Christian

Fine night last night but pretty warm at 20 degrees. SGP cooled the camera down to -20 (40 below ambient - better than the spec of 35) using 100% cooler power. I did a focus run then kicked off a sequence.

But SGP warned about the temperature which had warmed to -13, still using 100% cooler power. I left the camera idle but it didn't cool down. Seems to be a bug. Maybe my cooling problem is a bug in the firmware of the camera. Something isn't idling when it should.

I eventually kicked off the sequence and the camera over 15 minutes cooled to -18 where it stayed all night. I suspect that the window heater stopped it getting down to -20 as it had in the beginning of the session.
