(ASCC, ASCC-2.5)
(2001 catalog compiled from modern sources)

The All-Sky Compiled Catalogue (ASCC) is a catalog of 2.5 million stars compiled by modern surveys (e.g., Hipparcos). It extends to a limiting magnitude in the range of 12 to 14 and includes photometry, proper motion, and parallax data (when available). A number of open clusters have been uncovered using it.
