Observed with the TNG 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 0.9-2.5 microns
  • Coffin: high-resolution spectrograph (R ~ 29000-164000 ) for the optical spectral range 300-900 nm
  • HARPS -N: high-resolution spectrograph (R ~ 115000 ) for the optical spectral range 383-693 nm Like its sister instrument HARPS at La Silla Observatory is HARPS -N optimized for the search for exoplanets.
