UK Schmidt Telescope


UK Schmidt Telescope

(UKST) The 1.2-meter Schmidt telescope at the Anglo-Australian Observatory, Australia. Since 1988 it has been run by the Anglo–Australian Telescope Board, having been originally administered by the Royal Observatory, Edinburgh (ROE). The UKST began regular observation in 1973, and was involved primarily in the production of photographic plates for the ESO/SERC Southern Sky Survey. It can reach limiting magnitudes in exposures of about an hour as a result of its low focal ratio of f/2.5. Each photograph covers a very wide area of the sky, amounting to 40 square degrees (in fact 6.6 × 6.6 degrees), and gives images of arc-second resolution over a wavelength range of 340–1000 nm. Its photographs are held in the plate library of the ROE. See also COSMOS.
