Telescopio Nazionale Galileo
The Telescopio Nazionale Galileo ( TNG ) is an astronomical telescope with a mirror diameter of 3.58 m located at the Roque-de-los-Muchachos observatory on the Canary Island of La Palma . The mirror is made of Zerodur glass ceramic with an aluminum coating . The telescope is very similar to the New Technology Telescope of the European Southern Observatory on La Silla , from which the design was derived. The TNG has been monitoring since 1998. It is operated by the Fundación Galileo Galilei - INAF, Fundación Canaria for the Italian national institute for astrophysics INAF .
Observation instruments are (as of 2012):
- Dolores: camera and spectrograph for the optical spectral range
- Nics: Camera and spectrograph for the near infrared 900 to 2500 nm
- Coffin: high-resolution spectrograph (R ~ 29000… 164000) for the optical spectral range 300 to 900 nm
- HARPS-N: High-resolution spectrograph (R ~ 115000) for the optical spectral range 383 to 693 nm. Like its sister instrument HARPS at the La Silla Observatory , HARPS-N is optimized for the search for exoplanets .
