Special gears made it possible to reproduce the planetary constellations with great accuracy. The lattice towers on which the fixed star spheres were mounted contained the projectors for the planets, the sun and the moon. The smaller spheres have been used for the projection of the constellations. ![]() In this way, a total of 9,200 artificial stars were superimposed on the domed sky. The actual "stars" were created using perforated copper foils – each hole corresponds to a star of exactly the right brightness and in exactly the right position. The Cosmorama was one of the first computer-controlled projectors: it could be controlled manually via a control panel or fully automatically via a computer.Īt the outer ends of the Cosmorama are two fixed star spheres, which project the northern and southern starry skies into the domed hall using a total of 32 projection lenses. The projector, which can be retracted into the floor, was able to display the starry sky in a lifelike manner, project all constellations pictorially into the dome and superimpose planets. The dumbbell-shaped Cosmorama star projector from Zeiss was the centrepiece of the Zeiss-Großplanetarium from its opening in 1987 until its modernisation in 2014. Historical star projector: ZEISS COSMORAMA 49 loudspeakers and 4 subwoofers in interaction with the newly installed full-dome projection system create impressive three-dimensional worlds for the eyes and ears. The Spatial Sound Wave System developed by the Fraunhofer Institute for Digital Media Technology (IDMT) provides an impressively spatial sound experience. The 3D software, which is based on astronomical databases, visualises the entire observable universe so that we can journey to the edge of the universe as we know it and vividly explain great astronomical ideas. Computer animations provide insights into the birth and death of stars, three-dimensional flights enable the exploration of planetary surfaces and the collision of entire galaxies can be simulated in a time-lapse. Visitors can not only see the stars from Earth, but also leave Earth and the solar system and embark on a three-dimensional journey through the universe. The combination of the new star projector with a high-resolution full dome projection sets new technical and content standards throughout Europe. The star projector is complemented by a multi-channel digital projection system with ten ZEISS VELVET video projectors for 360° full dome projection, creating a video image that fills the entire dome. In addition, eight planet projectors show the movements of the planet stars in the firmament. It was specially modified for the building and projects the night sky in natural brilliance onto the 23-metre-high dome. Since 2016, a ZEISS UNIVERSARIUM Model IX star projector has been the new centrepiece of the Zeiss-Großplanetarium. Star projector: ZEISS UNIVERSARIUM Model IX
