|No star of the constellation exceeds the magnitude 3,5.
|Weak constellation of the southern hemisphere, to the south of Sagittarius.
The only interesting object is delta Telescopii, a couple of independent white-blue stars: they are both of fifth magnitude and they can be separated with simple binoculars.
|The constellation was drawn by Nicolas Louis de La Caille in 1756. It represents a long refracting telescope, similar to that used in the XVII century by Gian Domenico Cassini at the Parisian observatory.
