Norton's Star Atlas is a set of 16 celestial charts, first published in 1910 and currently in its 20th edition under the editorship of Ian Ridpath.The Star Atlas covers the entire northern and southern sky, with accompanying reference information for amateur astronomers.
In astronomy, a planisphere (/ ˈ p l eɪ. n ɪ ˌ s f ɪər, ˈ p l æ n. ɪ-/) is a star chart analog computing instrument in the form of two adjustable disks that rotate on a common pivot. It can be adjusted to display the visible stars for any time and date.

A simple chart for classifying the main star types using Harvard classification In astronomy , stellar classification is the classification of stars based on their spectral characteristics. Electromagnetic radiation from the star is analyzed by splitting it with a prism or diffraction grating into a spectrum exhibiting the rainbow of colors ...
[1] [2] [a] It was a central concept in a number of ancient sciences, providing the framework for key measurements in astronomy, astrology and calendar-making. From the perspective of an observer on Earth, the Sun's movement around the celestial sphere over the course of a year traces out a path along the ecliptic against the background of ...
Historically, optical astronomy, which has been also called visible light astronomy, is the oldest form of astronomy. [59] Images of observations were originally drawn by hand. In the late 19th century and most of the 20th century, images were made using photographic equipment.
Celestial cartography, [1] uranography, [2] [3] astrography or star cartography [citation needed] is the aspect of astronomy and branch of cartography concerned with mapping stars, galaxies, and other astronomical objects on the celestial sphere. Measuring the position and light of charted objects requires a variety of instruments and techniques.
