Digital Access to a Sky Century @ Harvard (original) (raw)

The Digital Access to a Sky Century @ Harvard (DASCH) is a project to preserve and digitize images recorded on astronomical photographic plates created before astronomy became dominated by digital imaging. It is a major project of the Center for Astrophysics | Harvard & Smithsonian. Over 500,000 glass plates held by the Harvard College Observatory are to be digitized. The digital images will contribute to time domain astronomy, providing over a hundred years of data that may be compared to current observations.
