About Dark Sky Observatory

Appalachian State University's Dark Sky Observatory (DSO) is the research facility used by faculty and their students to conduct observational research in astrophysics. It is equipped with four telescopes, each used regularly for CCD imaging and photometry, with spectrographic instrumentation also used at the 32-inch.

Established in 1981, the observatory is located about 20 miles northeast of Boone at an elevation of a kilometer. Far from major cities, its dark skies provide a good setting for digital imaging and spectroscopy done in stellar and solar system research projects. Details about the instrumentation and capabilities of the various telescopes is available at the Facilities link at the top of this page.
