USNO Image and Catalog Archive Server
This is a USNO facility that permits users to extract portions of star catalogs, create finding charts, and overlay them on digital images of the sky. The catalog and image archive contains the digital scans of a number of the major Schmidt telescope surveys of the skies, along with catalogs of astronomical objects created from those images. The NOMAD, USNO-B1.0 and USNO-A2.0 catalogs are available from here.
