Tisch Hall, named for donors Preston and Joan Tisch, is also connected to Angell Hall. The Angell Hall Observatory is located on the fifth floor roof of Angell Hall. The main telescope is a 0.4-m (16-inch) Ritchey-Chretien reflector, which has a spectrograph and camera. The observatory also has a small radio telescope and 20-cm (8-inch) Schmidt-Cassegrains.
