For telescopes and lenses aperature has nothing to do
with magnification but focal length does.

When you come up with a reason let us know.

I thought you said you were making some sort of
refactor out of the CCD chips. Will you be putting a
lens in front of them to focus the light? If so then
that is done by many people. It is not much different
than attaching a film camera to the scope. I assumed
you were not talking about that because it is quite
common. It works equally well with either reflectors
or refractors.
