A question about F/Ratings
I am still gathering information on the scope(s) I will eventually get ...
Having looked, and looked, and read whatever I can find, I am not 100% sure on what the F/rating has to do with anything scope-related.
I understand that a 200mm diameter, 800mm focal length scope has an F/4 rating, but what does this mean for me, the very average user?
Is an f/4 telescope necessarily better or worse than an f/10 one? I am assuming that the f/number is listed for a reason on your average telescope.
Experts, the floor is yours, with thanks ...
