The William Herschel Telescope (WHT) is a 4.2 metre optical infrared telescope, part of the Isaac Newton Group of Telescopes (ING) on La Palma in the Canary Islands. The ING is owned by STFC and is operated in collaboration with the Netherlands and Spain.
The William Herschel Telescope is the largest optical telescope of its kind in Europe, with a 4.2-metre primary mirror. It is a general-purpose facility, instrumented to allow a wide range of astronomical observations, from the optical wavelengths to the infrared. Through continued development of instrumentation, the William Herschel Telescope remains at the forefront of astronomical research.
