Constellation Reticulum (Reticle)

Reticulum: IAU Constellation Map [150]


The rhomboid shape of the small constellation is somewhat reminiscent of the dolphin constellation of the northern sky. Reticulum is easy to find because it is just northwest of the Large Magellanic Cloud. The area of Reticulum is 114 square degrees and the center culminates around midnight on November 19th. [9, 15]

Reticulum, the net, does not mean a fishing net, although it is not far from the Argo Navis, but a net engraved on glass in the telescope eyepiece, with which star positions were previously measured. This constellation was christened in 1624 by Bartsch Rhombus and later in 1752 by Lacaille Reticulum Rhomboidalis (Rhombic Network). It is intended to remind of this important astronomical measuring device. [7, 10, 21]
