OK, I have had Moravian and SBIG and QSI cameras and never seen anything like this. I have a new QHY ASI2600M and have tried both the native driver (in NINA, the native driver does not work in SGP) and the ASCOM driver (latest, of course), in SGP (both the with the last 3.X and the latest 4.X SGP). The camera simply will not cool with the ASCOM driver. Yes the fan runs, yes is does have DC power and it DOES cool fine with the native driver in NINA.
With the ASCOM driver, the cooler stays at zero percent and the camera stays at ambient, despite me setting the camera to cool to -10 C. It behaves this way in both NINA and SGP if I use the ASCOM driver, it does not matter if I select #1 or #2…
I do also have an uncooled ZWO guide camera plugged in but that is not the one selected in driver setup (the 2600 is selected) and disconnecting the guide camera made no difference in any case.
I have posted this to the ZWO forum but no reply as yet as well as to the NINA forum where no one has replied either.
Anyone seen this?
