Thanks,

Jason, I have taken 3 dark frame Screen Grabs for you.
They are at x128, x256, and x512 sens-up.

I left the Brightness and Contrast at 50% for all of them so they are equal in settings.

One thing I noticed straight away. Not as many hot pixels show up in these tests as when I image through the scope.
This test is with the camera out of the scope, lens cap on, and inside the house with the house heater on.
I see more hot pixels when the camera is in the scope, outside in the cold

Tomorrow night I will be broadcasting again, so I'll do an 'outside' test because I believe that this 'inside' test gives no results of any value. But for now, here are the results from this 'inside in the warm house' test.
