Crater Constellation Map

图像

图注： The constellation Crater with its bright stars and surrounding constellations. Crater is surrounded by (going clockwise from the top): Leo, Sextans, Hydra, Corvus and Virgo. Crater is a southern constellation so the whole of the cluster is visible at some point in the year from the whole of the southern hemisphere.The whole constellation is also visible from temperate and equatorial regions of the northern hemisphere. The constellation is best viewed in the evening in the northern hemisphere spring and southern hemisphere autumn. The y-axis of this diagram is in degrees of declination with north as up and the x-axis is in hours of right ascension with east to the left. The sizes of the stars marked here relate to the star's apparent magnitude, a measure of its apparent brightness. The larger dots represent brighter stars. The Greek letters mark the brightest stars in the constellation. These are ranked by brightness with the brightest star being labeled alpha, the second brightest beta, etc., although this ordering is not always followed exactly. The dotted boundary lines mark the IAU's boundaries of the constellations and the solid green lines mark one of the common forms used to represent the figures of the constellations. The blue line at the top left of the diagram marks the ecliptic. Neither the constellation boundaries, nor the line marking the ecliptic, nor the lines joining the stars appear on the sky.

Corvus Constellation Map

图像

图注： The constellation Corvus with its bright stars and surrounding constellations. Corvus is surrounded by (going clockwise from the top): Virgo, Crater and Hydra. Corvus is a southern constellation and thus the whole of the constellation is visible in the southern hemisphere at some point in the year. The whole constellation is also visible from temperate and equatorial regions of the northern hemisphere. Corvus is best viewed in the evenings in the northern hemisphere late spring and southern hemisphere late autumn. The y-axis of this diagram is in degrees of declination with north as up and the x-axis is in hours of right ascension with east to the left. The sizes of the stars marked here relate to the star's apparent magnitude, a measure of its apparent brightness. The larger dots represent brighter stars. The Greek letters mark the brightest stars in the constellation. These are ranked by brightness with the brightest star being labeled alpha, the second brightest beta, etc., although this ordering is not always followed exactly.

Telescopium Constellation Map

图像

图注： The constellation Telescopium with its bright stars and surrounding constellations. Telescopium is surrounded by (going clockwise from the top): Corona Australis, Ara, Pavo, Indus, Microscopium and Sagittarius. Telescopium is a southern constellation and thus the whole constellation is visible at some point in the year throughout the southern hemisphere. The whole constellation is also visible in equatorial and some temperate regions of the northern hemisphere. Telescopium is best viewed in the evening in the northern hemisphere summer and southern hemisphere winter. The y-axis of this diagram is in degrees of declination with north as up and the x-axis is in hours of right ascension with east to the left. The sizes of the stars marked here relate to the star's apparent magnitude, a measure of its apparent brightness. The larger dots represent brighter stars. The Greek letters mark the brightest stars in the constellation. These are ranked by brightness with the brightest star being labeled alpha, the second brightest beta, etc., although this ordering is not always followed exactly.

Lepus Constellation Map

图像

图注： The constellation Lepus with its bright stars and surrounding constellations. Lepus is surrounded by (going clockwise from the top): Orion, Eridanus, Caelum, Columba, Canis Major and Monoceros. Lepus is a southern constellation and thus the whole constellation can be viewed at some point in the year throughout the southern hemisphere. The whole constellation can also be viewed from temperate and equatorial regions of the northern hemisphere. Lepus is best viewed in the evening in the northern hemisphere winter and southern hemisphere summer. The globular cluster M79 lies in Lepus. It is marked here with a yellow circle with a plus sign superimposed on it. The y-axis of this diagram is in degrees of declination with north as up and the x-axis is in hours of right ascension with east to the left. The sizes of the stars marked here relate to the star's apparent magnitude, a measure of its apparent brightness. The larger dots represent brighter stars. The Greek letters mark the brightest stars in the constellation. These are ranked by brightness with the brightest star being labeled alpha, the second brightest beta, etc., although this ordering is not always followed exactly.

Fornax Constellation Map

图像

图注： The constellation Fornax with its bright stars and surrounding constellations. Fornax is surrounded by (going clockwise from the top): Cetus, Sculptor, Phoenix and Eridanus. Fornax is a southern constellation and thus the whole constellation is visible in the whole southern hemisphere at some point in the year. The whole constellation is also visible from equatorial and most temperate regions of the northern hemisphere. Fornax is best viewed in the northern hemisphere winter and southern hemisphere summer. The spiral galaxy NGC 1097 lies in Fornax and is marked here with a red ellipse. The y-axis of this diagram is in degrees of declination with north as up and the x-axis is in hours of right ascension with east to the left. The sizes of the stars marked here relate to the star's apparent magnitude, a measure of its apparent brightness. The larger dots represent brighter stars. The Greek letters mark the brightest stars in the constellation. These are ranked by brightness with the brightest star being labeled alpha, the second brightest beta, etc., although this ordering is not always followed exactly.
