[Scope of utility model registration request]

It consists of a constellation board on which the constellations of all seasons in the sky are drawn, and a mask board that covers the outside of the window corresponding to the horizon.By rotating the constellation board and the mask board, the constellations at a specific date and time can be read. In the planisphere displayed in the window, a light source that irradiates ultraviolet rays and a fluorescent layer containing a fluorescent material that emits light by the ultraviolet rays from the light source are formed on the constellations and other necessary parts, and the parts other than the constellations and other necessary parts are formed. A planisphere characterized by comprising: a constellation disk on which a light-shielding layer is formed;
