Clearance educative for recognizing constellations

摘要

The present invention relates to an educational game for recognition of the constellations present in the sky every day of the year. This game includes a cylindrical housing 10 whose cross-section exhibits the shape of a dodecagon and a cover 11 which can be fitted to this housing and bearing a rotating disc 14 representing the map of the sky. A fixed mask 12 including an aperture 13 corresponds to the visible part of the sky at the place of observation. This housing contains a light source and an optical protection device and the rotating disc 14 carries a reversed image of the sky in order to make it possible to reproduce the map of the sky in projection. This game is advantageous in that it makes it possible to make a small-scale model planetarium available to all, and especially to children. IMAGE
