PRIMER PROYECTOR PLANETARIO CARL ZEISS

ZEISS completed the development of the first projector for planetariums in August 1923 – enabling a projection planetarium's representation of the artificial night sky to be observed for the first time at the ZEISS facilities in Jena. The ZEISS projector was then brought to the Deutsche Museum, where it provided lifelike representations of cosmic happenings and planetary movements until 1960.
