(With say 3 arcsec seeing I can still get "good" imaging with a sampling of 0.8 arcsec/pixel)
Ok I guess I should have been more clear, this is visual. I have another scope for EAA, frame stacking, at f5.

Your 250X is pretty much in agreement with my recent experience with the CC8 ( with 266X being a practical limit on test nights).
