This is an engineering model of one element of a four- telescope array called Celescope which was half of the payload for the second Orbiting Astronomical Satellite (OAO II), launched in December 1968. Developed at the Smithsonian Astrophysical Observatory, Celescope was designed to survey the entire ultraviolet sky, looking for unusually hot sources of energy. Each telescope contained a 12-inch Cassegrain optical system and was equipped with a special Uvicon television tube and filters. The data from Celescope resulted in a catalog of over 5,000 ultraviolet colors for stars. Transferred from the Smithsonian Astrophysical Observatory.
