That's the problem, without sufficient resolution you can't tell the difference between signals and noise. You'll also be missing out on stuff. Call me old-fashioned, but if I'm going to go to the effort of taking the picture, I want it to show all that is possible. I'd rather double the focal length, dither and do a mosaic of the resultant images to get my 80k stars.

BTW I only counted 65,763 stars, so the rest must be noise
