Ooh, you're hurting my head. Okay, so the angular resolution of the
telescope is dependent on the aperture. But how can that have anything to
do with the size of the Airy disc, if the size of the Airy disc is
dependent on the F/#? It seems to me that if the angular resolving power of
the scope is dependent on the Airy disc size, then the angular resolving
power is also dependent on the F/#.

Is this somehow tied to the magnification of the scope plus eyepiece plus
eyeball combination?

Thanks to all who wrote in saying that I was right, before.
