Night Visitors at Steward Observatory
Steward Observatory's 2.3-meter Bok Telescope (also known as the 90-inch) is one of the largest telescopes on Kitt Peak. Built in 1969, the telescope is used for both imaging and spectroscopy by astronomers from University of Arizona, Arizona State University, and Northern Arizona University. The telescope is named in honor of Bart Bok, the prolific astronomer and director of Steward Observatory from 1966–1969.
