I cut and pasted the post into the QHY forum right after I posted on SGP.
They're not using ASCOM, but yes, in the ASCOM properties I checked to be
sure that the GAIN was set to 4 (you can see in the fit header for their
file that the gain was set to 4).
Is there anything in SGP that resets the gain (like you can select
different binning) that would override the ASCOM properties?
Thanks,
Glenn
