Clear Skies! is a Macintosh shareware program that brings you the night sky on your desktop. It draws a picture of the sky and sets it as the desktop picture.
You can choose the time and date and enter a location anywhere on earth and the sky is calculated accordingly. There's a lot of display options to set like show/hide constellations, coordinate grid, names of constellations, deep sky objects and more.
