Sky Screensaver

content:

This is a must-have for any serious astronomy buff. We say serious because this is a somewhat technical product (look for New Frontiers if you just want cool outer space pictures). This screen saver uses the Yale Bright Star Catalogue of more than 9000 stars to display stars, the Moon, the Sun,and the known planets in their correct position/phase in the sky, as well as more than 500 other deep-sky objects. Constellations can be mapped and identified as well as Bayer/Flamsteed designations, and much more.
