SkyMap is a "Planetarium" program that will display a map of the sky as seen from any point on Earth for any date between 4000BC and 8000AD. Two different types of maps can be drawn - a "Horizon" map showing the observer's local horizon, and a "Sky Area" map showing a detailed view of a small area of the sky. You can get information about any object displayed on the map by simply pointing at the object with the mouse and clicking the button.
