I am just glad that I finally made a decision on the camera. I had to take the plunge and now there's no looking back.

Would the ATIK be a good match for the RC10" and longer subs imaging planetary nebula?

Just plug your RC FL in mm in the formula below and it will give you your image scale. Anything around 1-1.5asp is good. 2-3 good for widefields. Under 1 to 0.5 need AO or very good seeing.
