The Heights Observatory, Astronomical observatory in Modbury Heights, Adelaide, Australia

The Heights Observatory consists of two buildings at The Heights School in Modbury Heights, Adelaide. The Emanuel Papaelia Observatory, opened in 1989, has a dome, while the Ingham Family Rooms, built in 1996, have a roll-off roof. The dome holds a 14-inch Meade LX-200 telescope, and the roll-off roof building houses a 12.5-inch Ritchey-Chrétien telescope.

The Emanuel Papaelia Observatory opened in November 1989 at The Heights School, housing a 1963 12-inch Dall-Kirkham Cassegrain telescope on loan from the Astronomical Society of South Australia, which had kept it at Marryatville High School. A second building with a roll-off roof, the Ingham Family Rooms, was added in 1996. In 2012 the school bought a 12.5-inch Ritchey-Chrétien and moved the 14-inch Meade into the dome.

The observatory is sometimes called the Adelaide Observatory, though it is not the former University of Adelaide observatory. On the Friday nearest the First Quarter Moon, roughly every two months, the Astronomical Society of South Australia holds a public viewing night, and STAR Group students demonstrate real-time imaging through the research-grade OGS telescope.

Public viewing nights run bimonthly, on the Friday nearest the first quarter Moon, at The Heights School in Modbury Heights. Members of the public look through the observatory telescopes and instruments brought by Astronomical Society of South Australia members. STAR Group students demonstrate real-time imaging on the research-grade telescope and show visitors through the 14-inch Meade in the dome.

The observatory's 12.5-inch Ritchey–Chrétien, bought by The Heights School in April 2012, is described as research-grade and space-certified, built by Optical Guidance Systems. STAR Group students use it to show real-time imaging to the public on viewing nights.
