The first star catalogue made by measuring photographs of the sky. The photographs were taken at the Cape Observatory, South Africa, by D. Gill in 1885–90, and star positions on them were measured in the Netherlands by J. C. Kapteyn. The result was a three-volume work published in 1896–1900, containing 454 875 stars down to 10th magnitude from −18° to the south pole.
