The Grange Observatory is a private scientific institution (established 1993, and certified with astrometry code MPC 476 in Circular 25095 of May 14th, 1995) located in Northern Italy 50 km W of Turin (details here), whose coordinates in several geodetic systems are:
The observatory with his homemade 300 mm mirror telescope is mainly devoted to astrometry (i.e. the accurate measurement of Solar System's moving celestial bodies, like comets/asteroids or even probes/satellites), collaborating with the International Astronomical Union's Minor Planet Center (MPC) of Cambridge, MA, U.S.A. and providing data for the planetary model DE405 to NASA JPL (ICRS/J2000 standard). The Grange Obs. astrometry observations of NEO asteroids are collected in the ESA funded NEODyS website; for the comets observation instead, see MPC Electronic Circulars. It has to be noted a dedicated study was conducted in 1995-96 for refining the orbital elements of NEO asteroid (433) Eros, since it was the target of the JPL spacecraft NEAR Shoemaker (which successfully entered in orbit around it, and afterwards landed on the asteroid's surface on February 12th, 2001). After the successful collaboration with JPL, the Grange Obs. has become a technology spin-off facility and a fundamental astronomy research center. In particular, contacts with JPL increased for the development of a methodology for studying the AMS 02 ISS payload position and pointing accuracy problem. In 2009 an off-the-shelf refractor was purchased (a Vixen 'Petzval' or double-achromat f/5.7 astrograph of 140 mm diameter) mounted on the main instrument as shown here below:
From 1995 to 2008 a parallel port CCD (512x512 pixel, 15 um) was used at the reflector first focus for astrometry and for star field imaging (22x22 arcminutes at 4 arcseconds/pixel)
