Abstract

The first dedicated catalogue of southern double stars was published in 1829 by
James Dunlop. Basing our work solely on the published data, we describe this catalogue, give a biography of Dunlop and a history of the catalogue and look at the data presented. Of the 253 doubles presented, Dunlop himself described one as single and 14 as triples. The smallest separation claimed was ~2 arcsec and limiting magnitudes were ~7 and ~8.5 for each of the two telescopes used. All observations were across the sky and approximately south of the Tropic of Capricorn.
