The SAC database is an amazing accomplishment. I know that Software Bisque uses it in their 'The Sky' software and it is the only database in that software that contains many important objects (like Barnard objects, for example).

Virtually nothing of the structure of the data has been changed, mostly poor typing in the NOTES and a few positions were in error. The Saguaro Astronomy Club prepared information on over 10,000 objects and are making that database available to the world for free. The entire Messier, NGC, PK and Barnard designations are covered. The best of the Trumpler, Lynds, Abell, Collinder and many others are available. We assembled this as a listing of all the objects available for worthwhile viewing in 6 or 8 inches of aperture and these objects are the most famous in the sky to those fortunate enough to have larger scopes.
