Sky Atlas Book- Written to fill a special need. More 2.5"(60mm) telescopes are sold than any other kind, but most star atlases assume at least a 6" or 8" telescope. We of course recommend that beginners start with a larger telescope, if possible, but the fact is most people start small. If you own a small telescope already you should supplement it with a pair of binoculars, learn to use the equipment you have, and start spending time under the stars. Featuring nearly 200 deep sky objects selected for visibility in a 2.5" telescope or simple binoculars, this atlas is designed to help you do just that. Click here to order by fax, or phone!
