William Herschel Telescope

(WHT, Herschel Telescope)
(4.2 meter telescope in the Canary Islands)

The William Herschel Telescope (or WHT or Herschel Telescope) is a 4.2 meter monolithic-mirror optical/near-infrared reflector telescope in the Canary Islands, operated by the Isaac Newton Group of Telescopes (ING). It came into service in 1987 as the world's fourth largest telescope and was early among modern large telescopes to use an altazimuth mount. WHT has now been dedicated to WEAVE (for WHT Enhanced Area Velocity Explorer), a multi-object spectrograph in the process of commissioning in 2023, and a large fraction of future WHT time will be for planned WEAVE-based surveys. Instruments listed before installation of WEAVE:
