Astrographic Catalog

(AC, Astrographic Chart)
(historical star catalog of the whole sky to magnitude 11)

The Astrographic Catalog was to be the product of an effort begun in 1887 to photograph the entire sky down to magnitude +11.5. As conceived, it would provide a reference of brighter stars for a simultaneous more-ambitious project, the Cart du Ciel, which would cover the sky to magnitude +14. The Astrographic Catalog effort was carried on for decades, the sky divided into more than twenty zones, assigned to individual observatories around the world. Eventually, as efforts dwindled over time, the USNO took up the project of completing it, which evolved into more modern efforts, such as the USNO CCD Astrograph Catalog. The plates produced by the earlier observatory efforts have been of use for comparison with recent efforts such as Hipparcos, in the study of proper motion
