WebMar 15, 2024 · A 200-mm (8-inch) telescope with a 2,000-mm focal length has a focal ratio of f/10. By contrast a 200-mm astrograph (a telescope designed for astrophotography) that has a focal length of 400 mm will have a focal ratio of f/2. Both telescopes collect the same amount of light, but the latter produces a much brighter image of your target.
