Originally called "chemical furnace". The stars in the constellation are dark. It is surrounded by the constellation Yufu in the west and the constellation Bojiang in the southeast, usually in the meander of a long string of dark stars in Bojiang, but it is not easy to distinguish it from these dark stars. There is a famous galaxy cluster on celestite.

Canolla is a very common constellation in an inconspicuous corner of the sky. The river represented by the constellation Bojiang flows by, and the north is the constellation Cetacea. Constellation was founded by French astronomer Llakaj in18th century, symbolizing the chemical melting pot. Sagittarius is a galaxy cluster 7500 light years away from the earth. The two brightest stars are NGC 13 16 and NGC 1365, which can be seen with a small telescope. NGC 13 16 is an abnormal spiral galaxy, which is called wireless power supply tower A; NGC 1365 is a rod-shaped spiral galaxy.

Although this constellation is not very south, it was not described by the French astronomer Llakaj until 1752. There are no stars with magnitude greater than +4 in this constellation, but it actually contains a galaxy cluster composed of various celestial bodies. It can only be seen with an 8-inch (20 cm) or larger telescope.
