Crater appears like a goblet tilted by 60 degrees to the left

Crater Constellation Map

image

Légende : 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.

Delphinus looks like a diamond with an additional small line extending to the south

Delphinus Constellation Map

image

Légende : The constellation Delphinus with its brighter stars and surrounding constellations. Delphinus is surrounded by (going clockwise from the top): Vulpecula, Sagitta, Aquila, Aquarius, Equuleus and Pegasus. Delphinus is a relatively small constellation with few bright stars. Delphinus lies just north of the celestial equator and thus the whole constellation is visible at some point in the year to all but the most antarctic regions. The constellation is best viewed in the evenings in the early northern hemisphere autumn and early southern hemisphere spring. The globular cluster NGC 6934 lies in Dephinus. 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.

Lepus appears as a crudely drawn rabbit without legs facing west

Lepus Constellation Map

image

Légende : 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.

Phoenix appears as a north-south diamond with a right-angled triangle extending from its western corner

Phoenix Constellation Map

image

Légende : The constellation Phoenix with its bright stars and surrounding constellations. Phoenix is surrounded by (going clockwise from the top): Sculptor, Grus, Tucana, Hydrus, Eridanus and Fornax. Phoenix is a southern 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 regions of the southern hemisphere with parts of the constellation visible to most temperate northern regions. Phoenix is circumpolar in antarctic and some temperate regions of the southern hemisphere. The constellation is best viewed in the northern hemisphere late autumn and southern hemisphere late 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. 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.

Reticulum appears as four stars in a kite shape pointing south west

Reticulum Constellation Map

image

Légende : The constellation Reticulum with its bright stars and surrounding constellations. Reticulum is surrounded by (going clockwise from the top): Horologium, Hydrus and Dorado. Reticulum is a southern constellation and thus the whole constellation are visible at some point in the year throughout the southern hemisphere. The whole constellation is also visible to most equatorial regions of the northern hemisphere, with parts of the constellation visible to the remaining equatorial and some temperate northern regions. Reticulum is circumpolar for all antarctic and most temperate regions of the southern hemisphere. The constellation is best viewed in the evening in the northern hemisphere winter and southern hemisphere summer. 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.
