Above the inversion layer on Mt. Wilson (video)

While the UCLA web cam on Mount Wilson's observatory is out of service, those who like a regular fix of San Gabriel Mountains sky can check out this video, "Above the Inversion Layer," by Elleni Sclavenitis. "Above the Inversion Layer evokes the perceptual alchemy that is the trade of astronomers and artists alike, both seeking to reveal some heretofore unperceived knowledge through observation and photography," she writes. "This single shot was recorded from the rotating catwalk of the 100-year-old telescope at Mount Wilson Observatory, located north of Los Angeles in the San Gabriel Mountains. Set to Gustav Holst’s The Planets, the video’s duration is the same as the composer's score."
