Pine Mountain Observatory (PMO) is an astronomical observatory owned and operated by University of Oregon Physics Department. It is located southeast of Bend, Oregon (USA) in the Deschutes National Forest.〔 The site was discovered by professors Russ Donnelly and E.G. Ebbinghausen in 1965 and has been in operation since 1967.〔〔 PMO's mission includes a strong public education aspect. Programs for high-school students have not only include observation, but also analysis of data and preparation of a paper for publication.〔 PMO has developed software that enables K-12 teachers to perform observations remotely and process the data for classroom use 〔 As well as public education, the observatory hosts professional projects such as research on white dwarf stars and examining the large-scale structure of galaxies.〔〔 ==Telescopes== * A Cassegrain reflector built in 1970 by Sigma Research has a 1024 x 1024 pixel thinned, rear illuminated, blue-sensitive CCD camera with a field size of approximately 36 arcminutes. It is mounted at the prime focus, which prevents direct observations.〔〔 * A Cassegrain reflector was the first telescope installed at the site in 1967.〔 * A Cassegrain reflector was used by Donnelly and Ebbinghausen before PMO was founded, and was later installed at the site.〔 As of 2007 a project was under way, in collaboration with Portland State University, to replace the historic instrument with a remotely controlled telescope for astronomical imaging.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Pine Mountain Observatory」の詳細全文を読む スポンサード リンク
