The University of Virginia operates a 10-inch (0.25 meter) f/4.5 astrograph at Fan Mountain Observatory, about 15 miles south of Charlottesville. The telescope is a wide field instrument with a 10° field of view using photographic plates. A gift of the Carnegie Observatories, it was originally used at McCormick Observatory by Alexander Vyssotsky with an objective prism to obtain spectra of stars over the entire 10° field. With this he produced one of the first catalogues of nearby M dwarfs.
