All I did with my test images

was to have the camera on the mount directly, no scope, with the 200mm lens. The cameras settings were 30 seconds in manual mode F5.4 (the smallest amount the lens would goto at 200mm) and had the timer on. so I clicked waited then exposed, then waited for the noise reduction to stop then looked... In the settings you have to turn on the long exposure noise reduction. I also shot in RAW.
