Thanks, Trevor. It does make sense, I think.
So, as far as photography goes, conditions and darkness could dictate which of these 2 scopes might do a better job on any given night. Under a light polluted sky, the 10" might actually produce a poorer photograph (albeit larger subject) because you might be expected to need longer exposures due to the higher F/stop. Whereas, shooting at a very dark site where longer exposures are less likely to be mucked up with light pollution, might as well use the 10", even with the higher F/stop, and take advantage of the higher magnification. Right?
