Isaac Newton Telescope

(ÿ -zăk new -tŏn) (INT) A 2.5-meter reflecting telescope operated by the Royal Greenwich Observatory at the Roque de los Muchachos Observatory on La Palma in the Canaries. It began operations in 1967 at the former RGO base in Herstmonceux, East Sussex, was dismantled in 1979, and, completely refurbished, resumed observations on La Palma in 1984. It is now part of the Isaac Newton Group. Its equatorial mounting was modified. Its new primary mirror has an extremely accurately figured paraboloidal surface made of Zerodur. The focal ratio is 2.9. There is an f/15 Cassegrain focus and an f/50 coudé focus. The latest developments in telescope instrumentation have been incorporated, including CCD and IPCS detectors. Observing time is shared between the UK, Spain, and the Netherlands.
