Lantern slide of the 30-inch reflecting telescope after it was rebuilt between 1925-1927. The dual-channel photoelectric photometer hangs on the end of the telescope. The rebuilt telescope was located in a 15-foot domed Observatory located on Florida Avenue south of Mount Hope Cemetery. The telescope was rebuilt by the local firm of J.B. Hayes for $1560 starting in January 1925. Baker announced its completion at the American Physical Society's annual meeting on December 29, 1927. This lantern slide is part of the Observatory's collection and is marked "PE 9."
