This is the theory.
The practice is that for large scopes (ie not 60mm refractors etc) other problems tend to limit resolution like the "seeing", tracking etc.

that is my understanding also. However for the hypothetical equipment setup I described, where both scopes are using cameras which give 1 arcsec per pixel, and both are operated under skies where seeing is limited to 2 arcsecs per pixel, is there any practical resolution gain from the larger aperture scope?
In fact on further thought, if the image scale is 1 arcsec per pixel for both, does it even matter what the seeing is? Even if the seeing was at 0.5 arcsec per pixel, if both scopes are using a camera which has an image scale of 1arcsec per pixel, then surely that is the resolution which is recorded ?
