Clive,
How about two 8" reflectors, one with a 1/4 PV wavefront spec, and other a 1/10 PV wavefront spec with the same secondary?
if mirror quality doesn't lend discernible differences for DSO's, does ccd quality be it build or sensor quality make more of a difference?
eg,similar spec'd qhy, sbig, FLI or other high end cameras? or is it sensor size similar to aperture with telescopes? bigger sensor, more detail?
I'm referring to a raw capture without any processing?
