I thought I'd share this find...

"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."

Personally, it's my favorite open-source software that I've found so far, even if I can't use it at work. :o)

The "red eye" feature is fab. There's been a few times I've taken my laptop down to the dark end of the beach at night and, by using the "red eye," there's very little glare to take away from seeing the stars. Love it!
