I noticed on the ZWO Product Page for the ASI2400MC Pro that the graphs for FW, RN, etc. show a gain range of 0 to 450. Yet when I access the ASCOM driver for this camera, I can only select gain between 0 to 300. What is the actual gain range for this camera? Is the 0 to 300 range in the driver the full minimum to maximum gain for this camera? Finally, is there any way to determine how much gain increase equates to 1 full stop of exposure?
