Rich, I have an interesting setup like this on my point and shoot.
I am using a Sony Mavica CD300 (3X optical zoom) with a CrystalVue LX8
scope mounted on the front. This should effectively give me 24X
optical zoom.

The interesting thing about this setup is that I shoot freehand and the
images come out crystal clear with no camera shake. My point and shoot
uses a Carl Zeiss f/2.0 lens.

With telescopes, because you can get projection eyepieces in virtually
any focal length,
it's possible to produce working focal lengths in the 500,000mm range.
But, where does the resolution peak? With the Zeiss, it's theoretical
maximum focal length with an optic
that large (16" wide) is around 40,000mm or 800 power. That is
assuming perfect "seeing conditions" no heat waves, no temperature
gradients.
