Re: Binos for Astronomy

I'd say -- after doing some astronomy with binoculars of a few different sizes -- that 10x50 is a really good all-around pair of binoculars. There is enough aperture to actually see many interesting things that won't show up in my 35s, for example, and they can be hand-held easily for long periods. Contrast that last bit with my 15x70s, where they can be held, but not for too long. 7x magnification is enough, and 15x is a little too much -- again -- to be held in the hand for an extended period.
Wide fields are good. Tripod mounts are good. A simple steel l-bracket ought to do it for most small to medium binoculars. I have a heavy tripod that I use for my spotting scope and my 90mm Mak when I want an alt/az setup. It has alt/az "setting circle" like markings on both axes. You can probably get something like that pretty easily if you want them, though I haven't ever used them even with the scope.
