Planetarium projector. A planetarium projector, also known as a star projector, is a device used to project images of celestial objects onto the dome in a planetarium. Modern planetarium projectors were first designed and built by the Carl Zeiss Jena company in Germany between 1923 and 1925, and have since grown more complex.
Zeiss projectors are designed to sit in the middle of a dark, dome -covered room and project an accurate image of the stars and other astronomical objects on the dome.

[11] The planetarium projector was a 13-foot (4.0 m)-long dumbbell-shaped object, with 29-inch (740 mm)-diameter spheres attached at each end ...
This projector displays about 8,900 different stars on the dome overhead. The analog planetarium shows are a combined effort of the Zeiss projector, slide projectors and video projectors working together to form a multimedia experience. Planetarium officials hope to display at least a portion of the projector somewhere in the center.
Digistar is the first computer graphics-based planetarium projection and content system.It was designed by Evans & Sutherland and released in 1983. The technology originally focused on accurate and high quality display of stars, including for the first time showing stars from points of view other than Earth's surface, travelling through the stars, and accurately showing celestial bodies from ...
