Coma Berenices Constellation Map
image
Caption: 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.

Canes Venatici Constellation Map
image
Caption: The constellation Canes Venatici with its brighter stars and surrounding constellations. Canes Venatici is surrounded by (going clockwise from the top): Ursa Major, Coma Berenices and Boötes.
Canes Venatici is a northern constellation and thus the whole constellation is visible at some point in the year from the whole of the northern hemisphere. The whole of the constellation is also visible from equatorial regions of the southern hemisphere with parts of it visible from temperate southern regions. The constellation is best viewed in the northern hemisphere late spring and southern hemisphere late autumn.
The famous spiral galaxy commonly known as the Whirlpool Galaxy (M51) lies in Canes Venatici and is marked here with a red ellipse. Other notable spiral galaxies in the cluster include M63, M94, M106 and NGC 4631. All are marked here with red ellipses. The globular cluster M3 is marked here with a yellow circle with a plus symbol 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.

Triangulum Constellation Map
image
Caption: The constellation Triangulum with its bright stars and surrounding constellations. Triangulum is surrounded by (going clockwise from the top): Andromeda, Pisces, Aries and Perseus.
Triangulum 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 most temperate regions of the southern hemisphere. Triangulum is best viewed in the evening in the northern hemisphere winter and southern hemisphere summer.
The Triangulum Galaxy M33 lies in the constellation. This spiral galaxy is the third largest member of the local group of galaxies after the Andromeda Galaxy and Milky Way. 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 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 left of the diagram marks the ecliptic. Neither the constellation boundaries, nor the lines joining the stars, nor the ecliptic, appear on the sky.

Caption: The constellation Fornax with its bright stars and surrounding constellations. Fornax is surrounded by (going clockwise from the top): Cetus, Sculptor, Phoenix and Eridanus.
Fornax is a southern constellation and thus the whole constellation is visible in the whole southern hemisphere at some point in the year. The whole constellation is also visible from equatorial and most temperate regions of the northern hemisphere. Fornax is best viewed in the northern hemisphere winter and southern hemisphere summer.
The spiral galaxy NGC 1097 lies in Fornax and is marked here with a red ellipse.
