(Center for High Angular Resolution Astronomy)
(optical interferometer)

CHARA, for Center for High Angular Resolution Astronomy, is a an optical interferometer located at Mount Wilson, California. It is an array of six 1 m telescopes, completed in 2003. It uses aperture synthesis with a maximum baseline of 330 meters, for an angular resolution up to 200 micro-arcseconds, equivalent to that of a (theoretical) single reflector telescope of that diameter.
