Hello Franco, I use a Logitech c600 bought years ago, that the NL Nederlands ( at that time ) scarce in economic, It was the resolution of at least 720p, Now they also come with higher resolutions.

I think in addition to a good resolution ( the ideal is 1080p ) not need anything, indeed the simpler, especially in the support, and best suited for use with various Foucault and Ronchi tests.

for the telescope, however, it is another matter altogether, more complex that I unfortunately am not able to get yourself thoroughly.
