The Isaac Newton Telescope is a research-grade optical facility located at the Roque de los Muchachos Observatory on La Palma. Operated by a consortium of UK universities and partners, it delivers high-quality imaging and spectroscopy for astronomers worldwide.
Originally commissioned at Herstmonceux in the United Kingdom, the telescope was relocated and upgraded on La Palma to exploit better atmospheric conditions. This upgrade has strengthened its role in time-domain surveys, exoplanet studies, and deep imaging campaigns.
