Built in 1953, it is located in Nashville, Tennessee, and is the only university facility not located on the main campus in Nashville. The observatory is named after Arthur J. Dyer, who paid for the observatory's 24-foot (7.3 m)-wide dome, and houses a 24-inch (610 mm) reflecting telescope named for astronomer Carl Seyfert.
The telescope is a Cassegrain reflector type with a 20.5-inch (52 cm) primary mirror. The mirror is one of many made by Corning Incorporated as a part of the research that allowed the pouring of the 200-inch mirror for the Hale Telescope.
