The Henry Draper Catalogue (HD) is an astronomical star catalogue published between 1918 and 1924, giving spectroscopic classifications for 225,300 stars; it was later expanded by the Henry Draper Extension (HDE), published between 1925 and 1936, which gave classifications for 46,850 more stars, and by the Henry Draper Extension Charts (HDEC), published from 1937 to 1949 in the form of charts ...

A first result of this work was the Draper Catalogue of Stellar Spectra, published in 1890. Williamina Fleming classified most of the spectra in this catalogue and was credited with classifying over 10,000 featured stars and discovering 10 novae and more than 200 variable stars. [53]
The following is a list of NGC objects, that is objects listed in the New General Catalogue (NGC). It is one of the largest comprehensive astronomical catalogues for deep sky objects such as star clusters, nebulae, and galaxies.

The Guide Star Catalog is an online catalogue of stars produced for the purpose of accurately positioning and identifying stars satisfactory for use as guide stars by the Hubble Space Telescope program. The first version of the catalogue was produced in the late 1980s by digitizing photographic plates and contained about 20 million stars, out ...
An astronomical catalog or catalogue is a list or tabulation of astronomical objects, typically grouped together because they share a common type, morphology, origin, means of detection, or method of discovery.
[8] [9] In response, the HCO began work on the first Henry Draper Catalogue, a long-term project to obtain the optical spectra of as many stars as possible and to index and classify stars by spectra. [10] Fleming was placed in charge of the Draper Catalogue project. [7] A disagreement soon developed regarding classifying the stars. [6]
In 1888, [3] Maury was assigned to observe stellar spectra of bright stars in the northern celestial hemisphere and catalog them. [1] [9] Her work contributed to the construction of the Henry Draper Catalogue. By 1924, the catalogue would contain 225,300 stellar spectra, described in terms of their characteristics. By 2017, it would have ...
