( June 2008)Ī determining fact source for drawing star charts is naturally a star table. More recently, computerized star maps have been compiled, and automated positioning of telescopes uses databases of stars and of other astronomical objects. Uranographers have historically produced planetary position tables, star tables, and star maps for use by both amateur and professional astronomers. These techniques have developed from angle measurements with quadrants and the unaided eye, through sextants combined with lenses for light magnification, up to current methods which include computer-automated space telescopes. Measuring the position and light of charted objects requires a variety of instruments and techniques. This print, published in Richard Blome's "The Gentleman's Recreation" (1686) shows the diverse ways in which cosmography can be appliedĬelestial cartography, uranography, astrography or star cartography is the aspect of astronomy and branch of cartography concerned with mapping stars, galaxies, and other astronomical objects on the celestial sphere.
