well if your looking for something like that, Do you know the angular resolution formula for telescopes. First find out what the angular resoloution for your telescope is, and im guessing find out what the size of your pixels are.!?

Remember that your telescope should have a greater angular resolution because the lense is way bigger than the human eye.

Angular Resolution R = Lambda/ Distance

Is the formula for this

λ is the wavelength of the observed radiation and D is the diameter of the telescope's objective lense. The resulting R is in radians.

Sources larger than the angular resolution are called extended sources or diffuse sources, and smaller sources are called point sources.

For example, in the case of yellow light with a wavelength of 580 nm, for a resolution of 0.1 arc second, we need D = 1.2 m.

A bit of basic algebraic manipulation of the formula will serve you with the answer you need im guessing.

anybody else ?
