Siding Spring Observatory near Coonabarabran, New South Wales, Australia, part of the Research School of Astronomy & Astrophysics (RSAA) at the Australian National University (ANU), incorporates the Anglo-Australian Telescope along with a collection of other telescopes owned by the Australian National University, the University of New South Wales, and other institutions. The observatory is situated 1,165 metres (3,822 ft) above sea level in the Warrumbungle National Park on Mount Woorat, also known as Siding Spring Mountain. Siding Spring Observatory is owned by the Australian National University (ANU) and is part of the Mount Stromlo and Siding Spring Observatories research school.
More than A$100 million worth of research equipment is located at the observatory. There are 44 telescopes on site (not all are in working condition).

The original Mount Stromlo Observatory was set up by the Commonwealth Government in 1924. After duty supplying optical components to the military in World War II, the emphasis on astronomical research changed in the late 1940s from solar to stellar research. Between 1953 and 1974, the 74-inch (1.9 m) reflecting telescope at Mount Stromlo was the largest optical telescope in Australia.
Already in the 1950s, the artificial lights of Canberra, ACT, had brightened the sky at Mount Stromlo to such an extent that many faint astronomical objects had been overwhelmed by light pollution. The search for a new site was initiated by Bart Bok. After a site survey was undertaken the number of possible locations was narrowed down to two — Siding Spring and Mount Bingar near Griffith, also in New South Wales. Siding Spring was first suggested for astronomy by Harley Wood, the New South Wales Government Astronomer at the time. Arthur Hogg did much of the preliminary site testing.
The Siding Spring site was selected by the ANU in 1962 from many other possible locations because of the dark and cloud-free skies. By the mid-1960s the ANU had set up three telescopes, together with supporting facilities, such as sealed roads, staff accommodation, electricity and water. In 1984, the Prime Minister, Bob Hawke, opened the ANU's largest telescope, the low-cost and innovative 2.3-metre (7 ft 7 in) aperture telescope, housed in a simple, co-rotating cuboid dome.
Since the 1950s, and quite independently of developments at Siding Spring, the Australian and British governments had been negotiating about the construction of a very large telescope. When these negotiations finally came to fruition in 1969, the infrastructure of Siding Spring Observatory was already in place, and it was the obvious site at which to locate the 4-metre (13 ft) aperture Anglo-Australian Telescope (AAT).
During the construction of the AAT in the early 1970s, the British Science Research Council also built the UK Schmidt Telescope, 1 kilometre (0.62 mi) to the northeast of the AAT dome. The considerably wider field of view of the Schmidt optical design complements the narrower field of the AAT, in that larger areas of sky may be surveyed more quickly. Interesting objects so discovered are then studied in greater detail on the larger instrument. In 1987, the Schmidt Telescope was amalgamated with the AAT.
Siding Spring Observatory also houses telescopes from Korea, Las Cumbres Global Telescope Network and the University of New South Wales. In 1990, the earth-satellite tracking facility of the Royal Greenwich Observatory was closed down after 10 years of operation. In 2012 the first publicly accessible Internet based observatory, working in partnership with the RSAA, was commissioned by iTelescope.Net with multiple telescopes housed in a large roll-off roof (ROR) observatory near the base of the UK Schmidt Telescope.
On 13 January 2013 the facility was threatened by a huge bushfire and firestorm. Eighteen staff were evacuated to Coonabarabran. Three buildings were destroyed: 'The Lodge' accommodation used by visiting researchers, the Director's Cottage and the Fire Station. Bushfire prevention measures had been implemented and were credited with the protection of the telescopes. Though smoke, ash and other air-borne debris entered some domes, all telescopes appear to have survived the inferno. The first telescopes back in action were those of the iTelescope Remote Observatory on January 20. The Anglo-Australian Telescope resumed normal operations in mid-February 2013.
There is a visitors' gallery and exhibition area open to the public which also incorporates a cafe and souvenir shop. During NSW school holidays, guided tours of the site are offered. Groups of over 15 adults may apply for Behind the Scenes walking or bus tours.
An Open Day is held annually in October, where visitors can enjoy many activities on site. They can listen to talks about astronomy, meet astronomers and tour inside many of the telescope domes which are open to the public on this one day of the year. These tours include the AAT 4M, UK Schmidt, iTelescope.Net, 2.3M ANU and the LCGTN 2M telescope facilities. Scenic views of the surrounding Warrumbungle National Park can also be enjoyed from its unique viewing point.

The Anglo-Australian Near-Earth Asteroid Survey used the UK Schmidt Telescope between 1990 and 1996. The same telescope was later dedicated for use by the RAVE survey of the Milky Way. The Near-Earth object search program called the Siding Spring Survey (closed 2013) used the Uppsala Southern Schmidt Telescope. The 2dF Galaxy Redshift Survey, one of the largest survey of galaxies ever undertaken used the Anglo-Australian Telescope between 1995 and 2002.
In 1977, the Vela Pulsar was discovered at Siding Spring. Comet 103P/Hartley was discovered by Malcolm Hartley in 1986. On 8 August 2006 C/2006 P1 was discovered by Robert H. McNaught using the Uppsala Southern Schmidt Telescope. On 3 January 2013 C/2013 A1, which will pass extremely close to Mars on 19 October 2014 at 18:28 ± 0:01 UTC, was discovered by Robert H. McNaught using the 0.5-meter (20 in) Uppsala Southern Schmidt Telescope.
