Faulkes Telescope South, Research telescope at Siding Spring Observatory, Australia

The Faulkes Telescope South is a research telescope with a 2-meter mirror diameter located at an elevation of 1,165 meters in New South Wales. It operates for observation sessions and scientific projects conducted by educational institutions from around the world.

The Faulkes Telescope South is a clone of the Liverpool Telescope and was funded by donations from philanthropist Dr. Martin C. Faulkes. It saw first light in 2004 and reached full operations in 2006 at Siding Spring Observatory. It is owned and operated by LCOGT, which allocates observing time to groups such as the Faulkes Telescope Project for UK schools.

The Faulkes Telescope Project, funded at the outset by donations from philanthropist Dr. Martin C. Faulkes, gives UK schools observing time on the telescope, awarded by LCOGT. Pupils and teachers use it remotely for their own projects rather than travelling to Siding Spring. Its twin, the Faulkes Telescope North, serves the same education groups in the northern hemisphere.

The telescope is not open to walk-in visitors; observing time is requested through the Faulkes Telescope Project, which awards slots allocated by LCOGT to UK schools. Sessions are run remotely, so groups need only a computer and internet connection rather than travel to Siding Spring. The site sits at Siding Spring Observatory in the Warrumbungle ranges of New South Wales.

On 4 May 2007 Marton Hidas and Tim Brown used the telescope to make the first observation of one Uranian satellite passing in front of another. The same instrument recorded the fast-spinning near-Earth asteroid 2008 HJ and imaged 2013 XY8 in 2013.
