Corona Borealis Constellation Map
image
Caption: The constellation Corona Borealis with its bright stars and surrounding constellations. Corona Borealis is surrounded by (going clockwise from the top): Boötes, Serpens Caput and Hercules.
Corona Borealis is a northern constellation and thus the constellation is visible from the whole northern hemisphere at some point in the year. It whole constellation is also visible from equatorial and most temperate regions of the southern hemisphere. The constellation 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. 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.

Crater Constellation Map
image
Caption: 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.

Caption: The constellation Grus with its bright stars and surrounding constellations. Grus is surrounded by (going clockwise from the top): Piscis Austrinus, Microscopium, Indus, Tucana, Phoenix and Sculptor.
Grus is a southern constellation and thus the whole constellation is visible at some point in the year from the whole southern hemisphere at some point in the year. The whole constellation is also visible from equatorial and some temperate regions of the northern hemisphere. Grus is best viewed in the evening in the northern hemisphere autumn and southern hemisphere spring.

Hydrus Constellation Map
image
Caption: The constellation Hydrus with its bright stars and surrounding constellations. Hydrus is surrounded by (going clockwise from the top): Eridanus, Phoenix, Tucana, Octans, Mensa, Dorado, Reticulum and Horologium.
Hydrus is a southern constellation and thus the whole constellation is visible in the southern hemisphere at some point in the year. As it lies close to the celestial south pole, only a small part of the northern hemisphere near the equator can see the whole of Hydrus, with other northern equatorial regions able to see parts of the constellation. Hydrus is best viewed in the evenings in the northern hemisphere winter and southern hemisphere summer.
This diagram maps an area around the south celestial pole. Here lines of constant right ascension converge. The right ascension values of these lines are marked on the x-axis above and below the diagram. The solid circle around the pole marks a line of -80° declination with the larger, incomplete circle to the right marking -70° declination. 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 Constellation Map
image
Caption: 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.
