U.S. Naval Observatory Flagstaff - 1.3-m Reflector

The 1.3-m Reflector

1.3-m Telescope

This is the newest telescope at the Flagstaff Station, completed in the late summer of 1999. The telescope is a modified Ritchey-Chretien optical design with a corrector lens designed to produce a very large well-corrected field 1.3-degees in diameter. A large-format mosaic CCD camera incorporating a 2x3 mosaic of 2048x4096 SITE CCDs takes advantage of this design, offering wide-field imaging with exellent astrometric properties. The telescope is operated completely automatically.
