Reticulum was introduced in the 1750’s by Lacaille to commemorate a grid-like device used during his surveys of the southern sky. This device is known as a reticle, which is used in telescope eyepieces for measuring star positions. The constellation  lies near the Large Magellanic Cloud, which lies in adjacent Dorado. It was originally known as Reticulum Rhomboidalis.

The suggested path to locate Reticulum is to create a line between Canopus, αCar, and Achernar, αEri.

Move to the midpoint of this line then drop toward the SCP a distance approximately 1/18th the length of the line, to arrive at αRet. The Large Magellanic Cloud (LMC) will be nearby to the celestial west-south-west.

αRet, is the brightest star in this constellation at magnitude 3.3. It is a yellow giant star 163ly away.
