    en.wikipedia.org/wiki/Southern_Celestial_Hemisphere

    Chart of the southern constellations from declination –40° to the south celestial pole by the Jesuit missionary François Noël published in Acta Eruditorum, 1711.. From the South Pole, in good visibility conditions, the Southern Sky features over 2,000 fixed stars that are easily visible to the naked eye, while about 20,000 to 40,000 with the aided eye.

    The Uranometria contained 48 maps of Ptolemaic constellations, a plate of the southern constellations and two plates showing the entire northern and southern hemispheres in stereographic polar projection. [19] Polish astronomer Johannes Hevelius published his Firmamentum Sobiescianum star atlas posthumously in 1690. It contained 56 large ...

    The depictions of the constellations in Urania's Mirror are redrawings from those in Alexander Jamieson's A Celestial Atlas, published about three years earlier, and include unique attributes differing from Jamieson's sky atlas, including the new constellation of Noctua the owl, and Norma Nilotica – a measuring device for the Nile floods – held by Aquarius the water bearer.

  5. Northern celestial hemisphere - Wikipedia

    en.wikipedia.org/wiki/Northern_celestial_hemisphere

    A star chart of the entire Northern Sky, centered on the north celestial pole. The northern celestial hemisphere, also called the Northern Sky, is the northern half of the celestial sphere; that is, it lies north of the celestial equator. This arbitrary sphere appears to rotate westward around a polar axis due to Earth's rotation.

    The two brightest northern stars are Vega and Capella. In the star chart to the right, declination is shown by the radial coordinate, starting at 90° north in the center and decreasing to 30° north at the outer edge. Sidereal hour angle is shown as the angular coordinate, starting at 0° at the left of the chart, and increasing counter-clockwise.

  8. IAU designated constellations by geographical visibility

    en.wikipedia.org/wiki/IAU_designated...

    The International Astronomical Union (IAU) designates 88 constellations. [1] In the table below, they are listed by geographical visibility according to latitude as seen from Earth, as well as the best months for viewing the constellations at 21:00 (9 p.m.).

  9. Planisphere - Wikipedia

    en.wikipedia.org/wiki/Planisphere

    The star chart contains the brightest stars, constellations and (possibly) deep-sky objects visible from a particular latitude on Earth. The night sky that one sees from the Earth depends on whether the observer is in the northern or southern hemispheres and the latitude. A planisphere window is designed for a particular latitude and will be ...
