I’ve watched Robin Glovers YouTube tutorials on Gain and exposure etc.. and enjoyed watching them very much , whilst very informative, interesting and theoretically correct , they don’t quite work with the latest batch of QHY and ZWO cameras that entered the market in the last 12 months as camera technology with these new Sony sensors has advanced so far since he presented those tutorials and is advancing every 6 months as well. In fact if you followed his proposed settings rigidly with these new cameras ( eg ZWOASI2600MC )you would not be taking advantage of the excellent performance of this camera with respect dynamic range , read noise etc.. as these new cameras have a QE of 80% +
