Welcome to Dark Sky Observing in Arizona.

Located on top of the Colorado Plateau in Northern Arizona along with Lowell Observatories in Flagstaff, Anderson Mesa, and the 4.2-meter Discovery Channel Telescope under construction in Happy Jack, the Apache-Sitgreaves Center for Astrophysics 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.
