The Spitz star projector accurately projects about 2300 stars onto the dome, which represents a dark-skies view of the naked-eye sky. In addition, there are individual projectors for the Sun, the Moon, and the five unaided-eye planets (Mercury, Venus, Mars, Jupiter, and Saturn). Sixteen strategically placed Ektagraphic slide projectors provide panoramic horizons. In addition, there are three fixed
dissolver slide screens, a rotator projector, a single axis fly-over projector, a two-axis movable projector, and a two-axis movable zoom projector. Fifty-five "special effects" projectors display constellation overlays, aurorae, supernovae, pulsars, meteors, warp-speed, and many other lighting effects. A video projector rounds out and enhances the equipment. There is also a surround-sound audio system, which gives each participant the feeling of "being there" in space. An East Coast Control System computer automated control system greatly enhances each planetarium program.
