The Isaac Newton Telescope (INT) has a 2.54-m diameter primary mirror. It uses a polar-disc/fork type of equatorial mount. Instruments can be mounted either at Cassegrain or Prime focus, offering the possibility to carry out both intermediate-low dispersion spectroscopy and wide-field imaging.
INT - HARPS-3
Visitor-mode observations at the INT ceased in mid-June 2024, and the telescope has been refurbished and roboticised, prior to installation of the HARPS-3 exoplanet hunter in 2025. No observing time is currently offered at the INT. It may be possible to offer open-time observing with HARPS-3 in 2026A.
