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. Discoveries 1977, the Vela Pulsar was discovered at Siding Spring. Comets discovered from the observatory include Comet 103P/Hartley, discovered in 1986 by Malcolm Hartley, Comet C/2006 P1, discovered by Robert H. McNaught using the Uppsala Southern Schmidt Telescope on 8 August 2006, and Comet C/2013 A1, also discovered by McNaught, which passed extremely close to Mars on 19 October 2014.
