i see. so if the image scale was greater than the size of the airy disk in both cases, there is nothing to be gained by using the 300mm over the 200mm ? but if that is not the case, then (assuming perfect seeing) the 300mm will deliver greater resolution?
And I take it that in my example where the f-ratio, and camera specs such as QE, noise etc are held constant, that exposure remains constant as well across both scope/camera combos....?
