The Galileo National Telescope, is a 3.58-meter Italian telescope, located at the Roque de los Muchachos Observatory on the island of La Palma in the Canary Islands, Spain. The TNG is operated by the "Fundación Galileo Galilei, Fundación Canaria", a non-profit institution, on behalf of the Italian National Institute of Astrophysics. The telescope saw first light in 1998 and is named after the Italian Renaissance astronomer Galileo Galilei.
Observations at the TNG can be proposed through the Italian Time Allocation Committee which assigns, based on the scientific merit of the proposals, 75% of the available time. The rest of the time is at disposal of the Spanish and international astronomical communities. The TNG is open to new proposals two times a year, typically in March–April and September–October.
