Star cartography

Star cartography, stellar cartography, celestial cartography, or uranography (Koine Greek ουρανος [IPA: ], "sky, heaven" + γραφειν [IPA: ] "write") is the branch of astronomy concerned with mapping the stars, galaxies, and a multitude of other celestial bodies. Positioning and measuring the light of charted objects requires a multitude of instruments, that have developed from bare-eye angle measurements with quadrants, later lenses for light magnification have been combined into sextants, and in the current age, computer automated space telescopes have been measuring up accurate star positions. Uranographers have historically produced planetary position tables, star tables and star maps fit for amateur and professional observations, nowadays computerized star maps, and automated positioning of telescopes are routinely using huge databases of stars and other astronomical objects.
