The Sculpteur is a Constellation of the Southern hemisphere, not very luminous.
History
Introduced by Nicolas-Louis de Lacaille in 1752 at the same time as 13 others to name a side of the southern sky without denomination, it was originally named “ the Workshop of the sculptor ” before its name is shortened.
Observation of stars
The constellation is weak, and its location is hardly of interest, if is not to locate the galactic Pole. If the conditions of visibility are good, it can rather easily locate starting from the southern Poisson: γ of the Sculptor is the weak star which closes two alignments of the Poisson. On the basis of γ, one easily finds β with 5° with the SE (on the road of the Phoenix and δ with 7° with. α is located at the height of δ, with about fifteen degrees more in the West (the small star halfway is ι Scl). The Southern galactic Pole is located at three degrees with NO of α Scl.

Most brilliant star of the Sculptor, α Sculptoris, does not exceed the Magnitude connect 4,30. β Sculptoris, γ Sculptoris and δ Sculptoris are very small little the least brilliant (magnitudes 4,38,4,41 and 4,59).
Celestial objects
The constellation of the Sculptor contains some objects of the deep sky, like the globular Amas NGC 288 or the Radiogalaxie S NGC 300 and NGC 613.The Groupe of the Sculptor is the galaxy cluster nearest to our local Groupe, to approximately 10 million light-years of distance. It includes/understands mainly the Spiral galaxy NGC 253 as well as a dozen other galaxies.
The southern galactic pole - one of the directions perpendicular to the plan of the Milky Way - is in this constellation.
