One benefit of the back-illuminated CMOS structure is improved full well capacity. This is particularly helpful for sensors with small pixels. Even with unbinned 3.76um pixels the QHY268C has a full well capacity of 50ke-
The QHY268C is a back-illuminated Scientific CMOS camera with extremely low dark current using SONY's Exmor BSI CMOS technology.In general, the fan-blade mechanical shutter will be broken if it is used 200,000 times or so, and in some specific cases it is easy to fail to switch on or off. The advantage of electronic shutter over mechanical shutter is high reliability and stability when the observatory shoots a large number of pictures. The electronic shutter is a relatively perfect choice for the observatory.
The round camera case design of QHY268C and the imager size is best match for Hyperstar systems.
