Zeiss-Jena Planetarium Projector
The planetarium projector was the focal piece of equipment at the planetarium. It was a Universal Projection Planetarium type 23/6, made by Kombinat VEB Carl Zeiss in Jena, in what was then East Germany.
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 representing the night sky for the northern and southern hemispheres. Connecting the two spheres was a framework that held nearly 150 individual projectors, including those dedicated to the planets, the Sun, and specific stars.
Improvements were made to the original planetarium projector over the years, allowing for special effects that could show close-up displays of specific planets, and the Sun and Moon projectors could replicate the experience of a solar or lunar eclipse.
The projector could be controlled by a console where an individual presenter would provide specific talks or lectures. By the mid-1970s, automation features were added, which led to the creation of prerecorded shows. Most visitors to the facility would have seen an automated 40- to 45-minute audio/visual show on a particular space-related topic. Two types of shows were typically alternated on a daily basis: one aimed at families with young children and another aimed at older children and adults. Typical shows aimed at both audience types were built around themes such as space travel, the mythical stories behind the constellations, and around Christmas-time, a show that investigated theories on stellar explanations for the Star of Bethlehem. A listing from 1970 includes shows titled The Story of Eclipses, which looked at how solar eclipses occur and their scientific importance, Man and the Zodiac which explored the history of mythology and astrology with regard to the night sky, and The Planet Venus which surveyed the history of the planet in mythology, the planet's motion across the sky and featured imagined views from its surface.

Famous quotes containing the word planetarium:
“In a large university, there are as many deans and executive heads as there are schools and departments. Their relations to one another are intricate and periodic; in fact, “galaxy” is too loose a term: it is a planetarium of deans with the President of the University as a central sun. One can see eclipses, inner systems, and oppositions.”
—Jacques Barzun (b. 1907)
