Digitized First Byurakan Survey (DFBS) Plate Scans
The First Byurakan Survey (FBS) is the largest and the first systematic
objective prism survey of the extragalactic sky. It covers 17,000 sq.deg.
in the Northern sky together with a high galactic latitudes region in the
Southern sky. This service serves the scanned objective prism images
and offers SODA-based cutouts.
