The Bok Telescope (also known as the 90-inch) is the largest telescope operated solely by Steward Observatory. It finds much use from astronomers from University of Arizona, Arizona State University, and Northern Arizona University, with instruments capable of both imaging and spectroscopy.[1] The telescope operates year-round, except during the August summer-shutdown when maintenance is performed while the weather is poor (Arizona's monsoon season lasts from roughly July through August).
