Quote:I've had the 8SE for 2 years now, and the only way I've checked collimation is with a visual star test. Unfocusing for that doughnut shape.Also, last night I tried the camera settings you mentioned with the histogram, and with gain at ~70, exp - 30 and gamma at 50, I was only getting about 38%..I had to move gain to 100 to get 48% histogram, but Saturn looked really, really bright and over-exposed.Thoughts?
