The Planetarium is located on the Stephen F. Austin State University campus and is operated by the Department of Physics and Astronomy. It has a Spitz 512 star projector under a 30 foot dome and a seating capacity of 50. The star projector can accurately simulate the night sky as seen from anywhere on Earth for any date in the past or future. When the room lights are darkened, the dome is transformed into an amazingly realistic simulation of the starry sky. The Planetarium's auxiliary equipment include 30 slide projectors, a large screen CRT video projector, laser disk and DVD players, a slew-zoom projector, special effects, an all-sky projection system and a red-blue-green special effects lighting system. All devices are controlled using a computer automation system. Since opening in 1983, the Planetarium has been presenting a wide array of entertaining and educational programs for schools and the general public.
