Baader Planetarium Solar demonstrator
An amazing device produced by Baader Planetarium in the mid 1960's. It lights up to projects stars in a darkened room. At the same time it shows the earth and moon revolving around the Sun. The moon in fact also revolves around the Earth. It has a light dimmer, planet speed control and can reverse direction.
