The Leitner Family Observatory and Planetarium, located on the campus of Yale University in Farnam Gardens. The Leitner Observatory is a facility of the Yale Department of Astronomy dedicated to education, public outreach, and student research.  We are open to the public every Tuesday night and Sunday afternoon.

Our digital planetarium theater uses a Spitz SciDomeHD system to simulate the Universe at any time from any place or to play back high-definition, fulldome videos. We use the planetarium to teach astronomy concepts in our undergraduate classes, to present programs for school groups in the New Haven area, to support astronomy programs at the Peabody Museum of Natural History, and to present planetarium shows to the general public. 

The observatory has two permanently mounted telescopes. The historic 8-inch Reed refractor, mounted in the east dome, was purchased by Yale in 1882 to study the transit of Venus across the face of the sun that occurred that year. The telescope was refurbished in 2004, and it is now used for visual observations of planets and stars. A computer-controlled, 0.4 meter reflecting telescope is mounted in the west dome. 

Inside the main building, we have a lecture hall with space for about 70 people where public lectures and some astronomy department classes and meetings are held. There are displays here about the history of astronomy research at Yale, and we have several historic instruments on loan from the Peabody Museum, including the 5-inch Dolland refractor, an historic instrument used by Yale astronomers Stiles and Loomis to spy the return of Halley's Comet in 1835.
