Re: A question from a total beginner

You guys have given some great advice!  I'm learning so much!

As I browse through different telescopes, I see different focal lengths (800mm, or 1100mm, etc).  Is this on the same scale as SLR lenses?  For example, should I be able to see four times as far with an 800mm telescope as I can with a 200mm lens on a full-frame SLR?  Or is there some sort of magnification factor I'm missing?
