ABSTRACT:
A construction kit for building a three-dimensional constellation model is disclosed for viewing of celestial maps. The kit includes a combination of (a) a zenith section having an external shape of a circular form, the back side of said zenith section having a celestial map of the zenith; (b) 6- to 24-in-a-set body plate sections each having a ship's bottom-like shape, each of said body plate sections including an overlap width on its upper edge for bonding to the zenith section, overlap widths on both its right and left edges for forming rib-like projections and an overlap width on its bottom edge for forming an annular flange, each plate section having a celestial map on its back side; (c) a flange-reinforcing plate adapted to bond together the overlap widths provided on the bottom edges of the adjacent body plate sections and (d) reinforcing plates for the rib-like projections to provide greater rigidity and strength to the completed model.
