ABSTRACT:
An astronomical optical simulator made of a tubular body with an eyepiece at one end and a light source at the other with a slot in the tubular member to receive an opaque disk having openings distributed to simulate an array of astronomical bodies. The openings modify and pass light from the source giving the impression of an array of astronomical objects to an observer looking into the eyepiece.
