Cassiopeia (Cas) Constellation, one of Three-Dimensional Astronomy Teaching Tools This constellation was designed to educate visually impaired individuals about astronomy. The diameter of each raised star indicates its relative brightness in the night sky. Raised lines connect the stars, forming a visual representation of the constellation's structure. This 3D model is scaled to fit within a 100 mm diameter space. To enhance visibility for those with limited vision, the stars can be painted with model aircraft enamel paint. Adding magnetic material to the back allows users to easily move the constellation around on a magnet board, such as a heating duct cover material. Each constellation is assigned a number instead of being directly labeled to facilitate classroom identification quizzes. A bead chain loop is located at the top of the disk for easy handling.
