Hi,
I just realized that the internal ADC bias setting of the camera (at least for my ZWO cameras) is not placed in the FITS header. The original ASICAP softare reports this (somewhat unlucky choice) as 'BRIGHT'. Not sure what other vendors call this. Is the name the reason it's not in the FITS, or is it not in the header for other cameras, either? If the latter - any chance putting it in?
