A robotic telescope with a 24-inch diameter main mirror and Ritchey-Chrtien optics was built for OSU by Optical Guidance Systems, Inc., and installed the week of February 915, 2007. It is the largest, most modern telescope in Oklahoma. It was funded by a $231,000 grant from the Air Force Office of Scientific Research in response to a proposal written by Professor Peter Shull, the observatory director. He and his research students will use it to track asteroids which threaten to collide with Earth, to photometrically discover planets orbiting other stars, and to measure the changing brightness of other objects whose light output varies with time.
