The Uppsala Schmidt Telescope was moved to Siding Spring Observatory from Mount Stromlo Observatory in 1980. Has field of view three times as large as the Anglo-Australian Telescope. Uses a spherical not parabolic mirror with 0.6m correcting plate to achieve this. Photographic plates and film used as detectors. Experimental use of CCD's (40x times more sensitive that photography). Used for discovering and retrieving asteroids. Safety patrol to identify "earth-grazers". This is the telescope with which the Great Daylight Comet of 2007 (C/2006 P1) was discovered by Robert H. McNaught.
