Crux Constellation Map
Bild
Unterschrift: The constellation Crux (commonly known as the Southern Cross or Crux Australis) showing its bright stars and surrounding constellations. The Southern Cross is surrounding by (going clockwise from the top) Centaurus, Carina and Musca. The brightest star is alpha Crucis which appears at the bottom of the constellation's famous kite shape. The Southern Cross is visible from southern and equatorial regions of the world. In more southerly parts of the world it is circumpolar so is always above the horizon. In other parts of the southern hemisphere and in equatorial regions it is most visible in the evenings in the southern hemisphere autumn.
The yellow circles show the locations of two open clusters, NGC 4755 (known as the Jewel Box) and NGC 4609.
The line joining gamma and alpha Crucis (the third and first brightest stars in the Southern Cross) points in the approximate direction of the South Celestial Pole. This has led to the Southern Cross playing an important role in celestial navigation, allowing navigators from different astronomical traditions to find their bearings.
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.

Waage-Sternbildkarte
Bild
Unterschrift: Das Sternbild Waage mit seinen hellen Sternen und den umliegenden Sternbildern. Die Waage ist im Uhrzeigersinn von oben gehend umgeben von dem Kopf der Schlange, Jungfrau, Wasserschlange, Zentaur, Wolf, Skorpion und Schlangenträger. Die Waage liegt auf der Ekliptik (hier als blaue Linie dargestellt), das ist der Weg, den die Sonne im Laufe eines Jahres über den Himmel zu nehmen scheint. Die Sonne befindet sich von Ende Oktober bis Ende November in der Waage. Die anderen Planeten des Sonnensystems sind oft in der Waage zu finden.
Die Waage liegt knapp südlich des Himmelsäquators und ist daher in allen Regionen mit Ausnahme der arktischsten im Laufe des Jahres irgendwann einmal sichtbar. Am besten zu sehen ist die Waage abends auf der Nordhalbkugel im späten Frühling/Frühsommer und auf der Südhalbkugel im Spätherbst/Frühwinter.
Die y-Achse dieses Diagramms ist in Deklinationsgraden mit Norden nach oben und die x-Achse in Stunden der Rektaszension mit Osten nach links. Die Größe der hier markierten Sterne bezieht sich auf die scheinbare Helligkeit des Sterns. Je größer die Punkte, desto heller scheinen die Sterne die sie darstellen. Die griechischen Buchstaben kennzeichnen die hellsten Sterne des Sternbildes. Diese sind nach Helligkeit geordnet, wobei der hellste Stern mit Alpha, der zweithellste mit Beta usw. bezeichnet wird, obwohl diese Reihenfolge nicht immer genau eingehalten wird. Die gepunkteten Begrenzungslinien markieren die IAU-Grenzen der Sternbilder und die durchgezogenen grünen Linien markieren eine der üblichen Formen, die zur Darstellung der Sternbilder verwendet werden. Weder die Sternbildgrenzen, noch die Linie, die die Ekliptik markiert, noch die Linien, die die Sterne verbinden, sind am Himmel sichtbar.

Caelum Constellation Map
Bild
Unterschrift: The constellation Caelum with its bright stars and surrounding constellations. Caelum is surrounded by (going clockwise from the top): Eridanus, Horologium, Dorado, Pictor, Columba and Lepus. Caelum is a relatively small and faint constellation.
Caelum is a southern constellation and the whole constellation is visible at some point in the year from the whole southern hemisphere and from equatorial parts of the northern hemisphere. Parts of the constellation are visible from temperate regions of the northern hemisphere. The constellation is most visible in the evenings 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. 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.

Leo Minor Constellation Map
Bild
Unterschrift: The constellation Leo Minor with its brighter stars and surrounding constellations. Leo Minor is surrounded by (going clockwise from the top): Ursa Major, Lynx, Cancer and Leo. Leo Minor is a small constellation with relatively few bright stars. It is a separate constellation from and should not be confused with its larger neighbour Leo.
Leo Minor 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 from equatorial and temperate regions of the southern hemisphere. Leo Minor is circumpolar in arctic regions. This constellation is best viewed 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 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 in the bottom right marks the ecliptic.

Circinus Constellation Map
Bild
Unterschrift: The constellation Circinus with its brighter stars and surrounding constellations. Circinus is surrounded by (going clockwise from the top): Lupus, Centaurus, Musca, Apus, Triangulum Australe and Norma. Circinus is a relatively small constellation with few bright stars.
Circinus is a southern constellation and is thus the whole constellation is visible from the whole southern hemisphere at some point in the year. The whole constellation can also be seen from some equatorial regions of the northern hemisphere with parts of the constellation visible from the remaining equatorial regions and some northern hemisphere temperate locations. The constellation is circumpolar for all antarctic and some southern hemisphere temperate regions. Circinus is best viewed in the evening in the northern hemisphere summer and southern hemisphere winter.
The open cluster NGC 5823 lies in Circinus and is marked here with a yellow circle.
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.
