The Telescopio Nazionale Galileo is a national facility of the Italian astronomical community that is located in La Palma. Since 2004 the Torino group have had an active service program "Parallaxes of sub-luminous L and T dwarfs" using the NICS camera. These objects are very interesting astrophysically because they represent exceptions to the normal trend of L and T dwarfs. Current work in underway to astrometrically calibrate the focal plane.
