Gornergrat Infrared Telescope

The Telescopio InfraRosso del GOrnergrat (TIRGO) is located on the northern tower of the Kulm Hotel at Gornergrat (3135 m altitude) near Zermatt. It was a 1.5m Cassegrain telescope with a tip-tilt correcting secondary and optimized for infrared observations, but was decommissioned in March 2005. The telescope and related instrumentation were run by the Istituto di Radioastronomia (IRA - C.N.R.), sezione di Firenze (former CAISMI) , with the assistance of the Osservatorio Astrofisico di Arcetri and the Dipartimento di Astronomia e Scienza dello Spazio of the University of Florence.
