Lupus Constellation Map

图像

图注： The constellation Lupus with its bright stars and surrounding constellations. Lupus is surrounded by (going clockwise from the top): Libra, Hydra, Centaurus, Circinus, Norma and Scorpius. Lupus 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 in equatorial and some temperate regions of the northern hemisphere with parts of the constellation visible to remaining temperate regions. Lupus is best viewed in the evenings 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. 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 in 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.

Scutum Constellation Map

图像

图注： The constellation Scutum with its brighter stars and surrounding constellations. Scutum is surrounded by (going clockwise from the top): Serpens Cauda, Sagittarius and Aquila. Scutum 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 from equatorial and temperate regions of the northern hemisphere with parts of the constellation visible from all but the most arctic regions. Two open clusters lie in Scutum: M11, commonly known as the Wild Duck Cluster; and M26. Both of these are marked here with yellow circles. 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 bottom of the diagram marks the ecliptic. Neither the constellation boundaries, nor the lines joining the stars, nor the ecliptic, appear on the sky.

Sextans Constellation Map

图像

图注： The constellation Sextans with its brighter stars and surrounding constellations. Sextans is surrounded by (going clockwise from the top): Leo, Hydra and Crater. Sextans is a small constellation with relatively few bright stars. Sextans spans the celestial equator and thus parts of the constellation are visible at some point in the year across the Earth. The whole constellation is visible in all but the most arctic and most antarctic regions. Sextans is best viewed in the evening in the northern hemisphere spring and southern hemisphere autumn. The lenticular galaxy NGC 3115 lies in Sextans. It 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. 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 of the diagram marks the ecliptic. Neither the constellation boundaries, nor the lines joining the stars, nor the ecliptic, appear on the sky.

Coma Berenices Constellation Map

图像

图注： The constellation Coma Berenices with its brighter stars and surrounding constellations. Coma Berenices is surrounded by (going clockwise from the top): Canes Venatici, Ursa Major, Leo, Virgo and Boötes. This constellation has relatively few bright stars. Coma Berenices is a northern constellation close to the celestial equator. As such the whole constellation is visible at some point in the year everywhere on Earth except the most antarctic regions. The constellation is best viewed in the evening in the northern hemisphere late spring and southern hemisphere late autumn. Coma Berenices is home to a large cluster of galaxies known as the Coma Supercluster. However none of the galaxies in this cluster are marked on this diagram as they are too faint to observe with most amateur telescopes. The elliptical galaxy M85 and the spiral galaxy M100 are members of the nearer Virgo cluster of galaxies. These are marked with red ellipses as are the even nearer M64 and NGC 4565, both of which are spiral galaxies. The globular cluster M53, marked here with a yellow circle with a plus sign superimposed on it, also lies in Coma Berenices. 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 bottom right 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.

图注： The constellation Piscis Austrinus with its bright stars and surrounding constellations. Piscis Austrinus is surrounded by (going clockwise from the top): Aquarius, Capricornus, Microscopium, Grus and Sculptor. Piscis Austrinus 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 to some equatorial regions of the northern hemisphere with parts of the constellation visible to the remaining equatorial and some temperate northern hemisphere regions. Piscis Austrinus is best viewed in the evening in the northern hemisphere autumn and southern hemisphere spring. 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.
