After quite a lot of reading about the best use of calibration for this camera it appears it’s best to skip the Bias altogether. Just do a master dark subtraction on the lights and do a flat dark (dark with the same duration as the flats).
I have in the past toyed with the super bias but found better results from just adding more to the master bias anyway. This was when I was using my QHY22 and not bothering with darks at all.
