I have an ASI2600MC Pro.  The Read Noise / Dynamic Range vs. Gain Plots at the ZWO link below range from 0 to 450.  I want to set the 2600 to a Gain of 100 per the plots so I get the best Read Noise and Dynamic Range from the camera.  The camera Gain settings in SGPro are 0 to 100.  It looks like an absolute scale.  The SGPro ASI Preset Drop Downs areā€¦

  • Highest Dynamic Range
  • Unity Gain
  • Lowest Read Noise
  • Manual

How can I set the camera to the Gain of 100 per the ZWO documentation at the link below?

Update - Apparently the the camera window that pops up belongs to ZWO - ASICamera Setup V 6.0.3.28.

It has nothing to do with SGP.  ZWO's ASCOM driver only goes to 100. As far as I know that's a true gain 100, not some sort of sliding scale where 0-100 equals 0-450.
