What’s Multiple Readout Modes and 2CMS Mode?

Multiple Readout Modes are special for QHY 16-bit Cameras (QHY600/268/461/411).  Different readout modes result in different performance. These readout modes are currently supported in the QHYCCD ASCOM Camera Driver, SharpCap and N.I.N.A. Readout Mode #0 (Photographic DSO Mode). This mode is suitable for most DSO imaging situations. Since there is a drop in the noise between Gain 25 and Gain 26 (unity gain), we recommend
