Cassiopeia Star Coin

Cassiopeia (Cas) Constellation

This is one of a collection of 3D constellations used to teach astronomy to the visually impaired. The diameter of the raised stars indicates the relative brightness. Raised lines connect the stars. It is scaled to 100 mm diameter. The stars can be painted with model aircraft enamel to make them more visible to those with limited vision. These can be easily moved around on a magnet board by adding magnetic material to the back (heating duct cover material). Each constellation is numbered rather than labeled directly for use as a classroom identification quiz. A bead chain loop is on the top of the disk.
