Cape Photographic Dürchmusterung (CPD)




A southern hemisphere extension of the Bonner Dürchmusterung and the first star catalogue produced from photographic measurements of the sky. The photographs were taken by the Scottish astronomer David Gill (1843–1914) at the Cape Observatory, South Africa, between 1895 and 1900, and the star positions on them measured by Jacobus Kapteyn in the Netherlands. The three-volume catalog, containing 454,877 stars down to 10th magnitude, between declination -19° and -90° (the south celestial pole), was published in 1896 to 1900.
