lower the better.
As you can see, the Readout Noise of the ASI294 camera is extremely low when compared with
traditional CCD cameras. In addition, it is with Built-in HCG mode, which can effectively reduce
read noise at high gain and keep the same wide dynamic range for this camera as at low gain.
When the gain is 120, the HCG mode will be automatically turned on. Additionally, the read noise
is as low as 1.2e while the dynamic range can still be close to 14bit.
Depending on your target, you can set the gain lower for higher dynamic range (longer exposure)
or set the gain higher for lower noise (such as short exposure or lucky imaging).
