Abstract
An automatic telescope (10) capable of determining an orientation without requiring input from a user or any external source. The telescope (10) preferably includes a database (22) to store astronomical information, a processor (24) to control a drive mechanism (18), a vision device (30) to sense bright stars, and a motion sensor (32) to generate a motion signal. When the vision device (30) is slewed from alignment with a first bright star to a second bright star, the motion signal is preferably representative of a measured angle between the first and second bright stars. This process is preferably repeated for several bright stars to generate several measured angles. The processor (24) can then use the measured angles to identify the bright stars and determine the orientation of the telescope (10).
