The Nordic Optical Telescope (NOT) is an astronomical telescope located at Roque de los Muchachos Observatory, La Palma in the Canary Islands. First light came in 1988, with regular observing beginning in 1989. It is funded by Denmark, Sweden, Iceland, Norway and Finland. Access is provided to astronomers of all nationalities through international time allocation committees.
The NOT was the first major telescope facility designed to use active optics to correct the shape of a thin, lightweight primary mirror supported on actuators. The main mirror has a diameter of 2.56 metres (101 in).
