http://stellarium.sourceforge.net/

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. This has been added to Astronomy Resources Subject Tracer™ Infomtion Blog.
