Is there a way to adjust the histogram of the red, green and blue channels of a CMOS camera like the QHY183C?
It would be interesting to balance the background of the sky during capture.
at least for the ASI294MC this adjustment is permanently written into the FITS, which is not optimal. It is a property of the ZWO Indi driver. On the „Controls“ tab in the driver you can adjust „WB-R“ and „WB-B“. But, as said, this is baked into the FITS raw image. I would leave the WB-R and WB-B at 50 (neutral gain) and do color correction in post.
