Coder, software architect, interest in computer science in general. Did research on computer graphics, ray tracing, radio wave and antenna simulation. Like to learn new programming languages. Currently doing Python and Emacs Lisp for fun. C++ for profit. Would like to learn more Clojure.

Well, it seems the angular resolution of a telescope can be approximated by the Rayleigh limit, which is 5.5/aperture in inches. So for 10 inch, this will be 0.55 arcseconds. And a quick search tells me that the ISS is about 37 arcseconds at 410km distance. So we get at least 67 clear ISS pixels out of the 10 inch telescope! Furthermore, using super-resolution techniques, we can achieve much better resolution than that.

Are the two black slices in the diagram due to the milky way blocking our view?

comment Is the light we see from stars extremely old?
4000 lightyears would mostly be still in our galaxy, which is roughly 100.000 lightyears across, and 3000-6000 lightyears thick. Most galaxies are at least millions of lightyears away.

I edited the question a bit, and would also be able to provide at least one answer.
