Urania's Mirror; or, a view of the Heavens is a set of 32 astronomical star chart cards, first published in November 1824. [1] [2] They are illustrations based on Alexander Jamieson's A Celestial Atlas, [2] but the addition of holes punched in them allow them to be held up to a light to see a depiction of the constellation's stars.

The Hebrew alphabet, along with other scripts like the Celestial Alphabet and runes, became central to the practices of the Hermetic Order of the Golden Dawn and Aleister Crowley’s Thelema. These systems often combined magical alphabets with astrological symbols , tarot , and numerology , creating powerful tools for ceremonial magic and ...
Ben — Jack Bennett's catalogue of 152 deep-sky objects in the southern celestial hemisphere, all from the NGC or IC lists, except Ben 47 which is Melotte 105 in Carina, and Ben 72a which is Trumpler 23 in Norma; Bergeron — Joe Bergeron (for example: Bergeron 1 in Cepheus) [9] BFS — Blitz-Fitch-Stark (for example: BFS 15 in Cepheus) [10]
The International Celestial Reference System (ICRS) is the current standard celestial reference system adopted by the International Astronomical Union (IAU). Its origin is at the barycenter of the Solar System , with axes that are intended to "show no global rotation with respect to a set of distant extragalactic objects".
The other two cover the equatorial region of the celestial sphere, from the declination of 30° south to 30° north. The two equatorial charts are mercator projections, one for the eastern hemisphere of the celestial sphere and one for the western hemisphere. Note that unlike familiar maps, east is shown to the left and west is shown to the right.
The Atlas Coelestis is a star atlas published posthumously in 1729, based on observations made by the First Astronomer Royal, John Flamsteed. [1]The Atlas – the largest that ever had been published and the first comprehensive telescopic star catalogue and companion celestial atlas [2] [3] – contains 26 maps of the major constellations visible from Greenwich, with drawings made in the ...
A diagram of a typical nautical sextant, a tool used in celestial navigation to measure the angle between two objects viewed by means of its optical sight. Celestial navigation, also known as astronavigation, is the practice of position fixing using stars and other celestial bodies that enables a navigator to accurately determine their actual current physical position in space or on the ...
The Hipparchus star catalog is a list of at least 850 stars that also contained coordinates of stellar positions in the sky, based on celestial equatorial latitude and longitude. [1] According to British classicist Thomas Heath, Hipparchus was the first to employ such a method to map the stars, at least in the West. [2]
