I'm slowly working through using PI for the first time and have arrived at the SubFrameSelector process.

I have a late-2016 ZWO1600MM-Cool and just want to check the correct resolution input for this camera, which I believe is 12-bits. Please can somone confirm this or otherwise?

Thanks

Note some ZWO drivers on 12-bit cameras multiply data by 16 to create 16-bit data.

One way to test: load a raw frame into PI which has some bright stars, open Statistics process, and check the maximum value. If the max is larger than 4,095 then this scale up has been done.
