Carlsberg Meridian Telescope

The Carlsberg Meridian Telescope (formerly the Carlsberg Automatic Meridian Circle) is located at Roque de los Muchachos Observatory in the Canary Islands. It is a meridian circle that is dedicated to carrying out high-precision optical astrometry. It is now decommissioned and its last night of observing was on 2013/09/01.[1]

Location of Carlsberg Meridian Telescope

The CMT was used to take photometric measurements and the data covering 20 years was studied to understand atmosphere extinction.[2] Up to 2003, 11 catalogs were published and it had been given various upgrades since its installation in 1984.[3]

The telescope is owned by the Danish Copenhagen University Observatory, but was operated with an international agreement with two other institutions.[3]
