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. 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. Neither the constellation boundaries, nor the lines joining the stars appear on the sky.

Sagitta Constellation Map

图像

图注： The constellation Sagitta with its bright stars and surrounding constellations. Sagitta is surrounded by (going clockwise from the top): Vulpecula, Hercules, Aquila and Delphinus. Sagitta is a relatively small constellation. Sagitta is a northern constellation and thus the whole constellation is visible at some point in the year throughout the northern hemisphere. The whole constellation is also visible to equatorial and temperate regions of the southern hemisphere. Sagitta is best viewed in the evening in the northern hemisphere summer and southern hemisphere winter. The globular cluster M71 lies in Sagitta. 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.

Hercules Constellation Map

图像

图注： The constellation Hercules with its bright stars and surrounding constellations. Hercules is surrounded by (going clockwise from the top): Draco, Boötes, Corona Borealis, Ophiuchus, Aquila, Sagitta, Vulpecula and Lyra. Hercules is a large, northern constellation that covers a big range in declination. The whole constellation is visible at some point in the year in the whole northern hemisphere and in equatorial regions of the southern hemisphere. Parts of the constellation can be viewed from temperate and almost all antarctic regions of the southern hemisphere. Hercules is best viewed in the northern hemisphere summer and southern hemisphere winter. The globular clusters M13 and M92 lie in Hercules and are marked here with yellow circles with plus signs superimposed on them. 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.

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.

Corona Australis Constellation Map

图像

图注： The constellation Corona Australis with its brighter stars and surrounding constellations. Corona Australis is surrounded by (going clockwise from the top): Sagittarius, Scorpius, Ara and Telescopium. This constellation has relatively few bright stars. Corona Australis is a southern constellation and thus the whole constellation is visible in the southern hemisphere at some point in the year. The constellation can also be viewed from equatorial and some temperate regions of the northern hemisphere. The constellation is best viewed in the evening in the northern hemisphere summer and southern hemisphere winter. The globular cluster NGC 6541 lies in Corona Australis and 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. 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. Neither the constellation boundaries, nor the lines joining the stars appear on the sky. The blue line at the top right of the diagram marks the ecliptic.

Musca Constellation Map

图像

图注： The constellation Musca with its bright stars and surrounding constellations. Musca is surrounded by (going clockwise from the top): Crux, Centaurus, Carina, Chamaeleon, Apus and Circinus. Musca 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 visible to a thin strip of the northern hemisphere near the equator with parts of the constellation visible to other northern equatorial regions. Musca is circumpolar in temperate and antarctic regions of the southern hemisphere. Musca is best viewed in the evening in the northern hemisphere late spring and southern hemisphere late autumn. The globular clusters NGC 4372 and NGC 4833 lie in Musca and are marked here with yellow circles with plus signs superimposed on them. 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.
