I would like to request ZWO to increase the 2600mm max gain setting from 100 to at least 200 on the "ASICamera Setup" software, ASCOM driver, as well as on the ASIAIR, so that it allows user to fully exploit the capacity of the sensor.
In some circumstance, I need higher ADU-to-electron ratio (i.e. gain) for low light photography. As a professional CMOS scientific camera company, why limit the freedom of use by professional?
I own both ASI2600mm and ASI533mc, and found that gain value range is less restrictive in ASI533mc.
