Mount Stromlo and Siding Spring Observatories

(strom -loh sÿ -ding) Optical observatories that are owned and run by the Australian National University, Canberra, and located on Mount Stromlo near Canberra, altitude 770 meters, and on Siding Spring Mountain, altitude 1150 meters, in the Warrumbungle range, New South Wales. The main instrument on Mount Stromlo is a 1.9-meter reflector acquired in 1953. At Siding Spring, where the seeing is much better, there is a 2.3-meter altazimuth reflector, operational since 1984, and some smaller reflectors. The Anglo–Australian Telescope and the UK Schmidt Telescope are also located at Siding Spring.
