The Bradley Observatory is an astronomical observatory owned and operated by Agnes Scott College. It is located in Decatur, Georgia, 5 miles east of Atlanta, Georgia, (USA). The observatory's largest telescope, the Beck Telescope, is a vintage 30 inch (750 mm) Cassegrain reflector built in 1930. The telescope was owned and operated by an amateur astronomer, Mr. Gibson. He offered the telescope for sale, seeking to upgrade his own telescope. Agnes Scott purchased it in 1947 for about $15,000.
