 It appeared as a stand-alone publication,
and as three volumes of the 17-volume "Hipparcos Catalogue".The 1548 charts include one million stars from the Hipparcos and Tycho-1 Catalogues, three times as many as in any previous all-sky atlas; more than 8000 galaxies with their orientation; outlines of many bright and dark nebulae; the location of many open and globular clusters; and some 250 of the brightest quasars.The non-stellar objects in the atlas are identified by type and designation.
