Yep.
The guys have pretty much nailed this one in their answers.
From my observations and reading what others have written on this website over many months, it appears to me an ED80 makes an excellent widefield photographic scope and a very nice finder/guide/spotting scope attached to an instrument of larger aperture which does the "real work"????
I'm not sure you'd want it as your one and only visual scope, though
I'll back what's already been said... aperture!
But they are great
little scopes.
