The Beginner''s Guide to Reflector Telescopes
An f/4 reflector will have a larger secondary mirror vs an f/8 reflector and will have a lower contrast (although the views of the nebula will be brighter). That being said, we recommend a faster reflector with a focal ratio of f/4-f/6 for astrophotography and f/6-f/8 for visual astronomy.
