Abstract
A device for simulating the movements of and representing rotation symmetrical bodies, such as planets, particularly for use in planetaria, comprising a reflecting member centrally inserted between two illumination systems. The reflecting member is provided with two reflecting faces carrying a step arrangement and including an angle of 90.degree. with one another. Each of the reflecting faces includes an angle of 45.degree. with an optical axis and lies in an intermediate plane into which slide photos of bodies to be reproduced are imaged. The reflecting member is displaceably and tiltably arranged and is followed by an image fusing lens. Furthermore, adjacent to the slide photos occulting members are provided.
