Well now…ain’t this interesting…has happened twice on my 314L+ since updating to 188.8.131.52. I’d written it off to a peltier going wonky.
Haven’t tested on (don’t have) any other software. Also agree with Ken…an ASCOM client shouldn’t really know or care about the hardware, so I could still believe it’s the cooler…, but…this DOES seem an odd coincidence.
Just noticed if I click the Settings Icon for the CCD in SGP, I get an ASCOM setup window that shows, among other things, the cooler power and CCD Temp. Next time i see this behaviour, I’ll pull that up and see if the numbers match…that would certainly narrow it down I think.
Also, @Mats, that same window has a checkbox for “Trace On”. That will enable an ASCOM log for the camera, which will be stored in your ASCOm documents directory (Usually My Documents/ASCOM/Logs YYYY-MM-DD)
