I've read a bunch of posts from noobie astronomers wondering what type of telescope to buy and noticed many people recommend getting a goodset of binocuars first. How much detail can you actually see with a set of binoculars (bodies other than the Moon, say Mars or a nebula)? Do they make binoculars that mount to a tripod or do you just stay as steady as you can? What types and power are recommended for star gazing? Thanks much!
