Horologium Constellation Map
image
Caption: The constellation Horologium with its bright stars and surrounding constellations. Horologium is surrounded by (going clockwise from the top): Eridanus, Hydrus, Reticulum, Dorado and Caelum.
Horologium is a southern constellation and thus is visible in the whole southern hemisphere at some point in the year. The whole constellation is also visible from equatorial parts of the northern hemisphere with parts of it visible to some northern temperate regions. Horologium is circumpolar in antarctic and some temperate regions of the southern hemisphere. This constellation is best viewed in the evenings in the northern hemisphere winter and southern hemisphere summer.
The globular cluster NGC 1261 lies in Horologium, 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.

Pavo Constellation Map
image
Caption: The constellation Pavo with its bright stars and surrounding constellations. Pavo is surrounded by (going clockwise from the top): Telescopium, Ara, Apus, Octans and Indus.
Pavo 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 some equatorial regions of the northern hemisphere with parts of the constellation visible in the remaining northern equatorial regions. Pavo is circumpolar in antarctic 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 globular cluster NGC 6752 lies in Pavo and is marked here with a yellow circle with a plus sign superimposed on it.

Musca Constellation Map
image
Caption: 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.

Apus Constellation Map
image
Caption: The constellation Apus with its bright stars and surrounding constellations. Apus is surrounded by (going clockwise from the top): Triangulum Australe, Circinus, Musca, Chamaeleon, Octans, Pavo and Ara.
Apus is a southern constellation lying close to the south celestial pole. As such it is visible at some point in the year from the entire southern hemisphere but is only visible from the most equatorial regions of the northern hemisphere. Apus is circumpolar for all temperate and antarctic regions of the southern hemisphere. It is most visible in the evenings in the northern hemisphere summer and southern hemisphere autumn.
The globular cluster NGC 6101 can be found in Apus. It is marked here with a yellow circle with a plus symbol superimposed on it.
This diagram maps an area around the south celestial pole. Here lines of constant right ascension converge. The right ascension values (in hours) of these lines are marked on the x-axis above and below the diagram. Lines of constant declination (in degrees) are marked on the y-axis. 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.

Chamaeleon Constellation Map
image
Caption: The constellation Chamaeleon with its bright stars and surrounding constellations. Chamaeleon is surrounded by (going clockwise from the top): Carina, Volans, Mensa, Octans, Apus and Musca.
Chamaeleon lies close to the south celestial pole and this the whole of the constellation is visible from the whole southern hemisphere at some point in the year. All or part of the constellation can be seen from equatorial regions of the northern hemisphere. The whole constellation is circumpolar for all but the most equatorial regions of the southern hemisphere. Chamaeleon is best viewed in the evenings in the northern hemisphere spring and southern hemisphere autumn.
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 circles above it marking -70° and -60° declination respectively. 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.
