Welcome to Dark Sky Observing, the web presence of Apache-Sitgreaves Research Center, a private research institution located in Overgaard, Arizona.

Located on top of the Colorado Plateau in Northern Arizona along with our famous neighbors; Lowell Observatories in Flagstaff and Anderson Mesa, and the 4.2-meter Discovery Channel Telescope in Happy Jack, the Apache-Sitgreaves Research Center in Overgaard, Arizona is located at a world class dark sky site at just under 7000 feet elevation.

The skies are not only extremely dark but very transparent, with sub-arcsecond seeing on most nights.
