These are companies I've purchased from and have been satisfied with. There is no other endorsement other than that.
Enerdyne – In Suttons Bay,a local source for telescopes and other astronomical and science items
Willmann-Bell, Inc - Source for astronomical books and atlases
Edmund Scientific - telescopes, binoculars and lots of other stuff
Stellarium – a great realistic planetarium program which is easy to use! “Stellarium is a free open source planetarium for your computer. It shows a realistic sky in 3D, just like what you see with the naked eye, binoculars or a telescope. It is being used in planetarium projectors. Just set your coordinates and go.” For Windows, Mac OS X and Linux.
Cartes duCiel – (Sky Charts) not as beautiful as Stellarium but a very robust star chart program with stars down to 12th magnitude and the ability to download hundreds of asteroid and comet orbits. I find this is better on a laptop than star charts at the telescope. Lots of star and object catalogs are available for it. It can supposedly drive a telescope, but I haven't tried it.
Celestia - “... space simulation that lets you explore our universe in three dimensions. Celestia runs on Windows, Linux, and Mac OS X. ”
Virtual Moon Atlas – This is the ultimate reference for studying the moon. “Used in several books, magazines, observatories, universities and Web sites. Used in Chandrayaan 1 lunar mission preparation. Recommended by the European Space Agency (ESA) and the French Ministry of National Education ” For Windows, Mac OS X and Linux.
Microsoft WorldWide Telescope - “WorldWide Telescope (WWT) enables your computer to function as a virtual telescope, bringing together imagery from the best ground and space-based telescopes in the world. Experience narrated guided tours from astronomers and educators featuring interesting places in the sky. ” A client can be downloaded for Windows or a Web client can be used for Mac.
Google Earth – (Contains also Google Moon, Google Mars and Google Sky) Roam these as easily as you can roam Google Earth.
