Telescopium, or the telescope is a medium constellation located in the South hemisphere and invisible from I write these lines to you, 40º of North latitude.
Telescopium is to the south of the constellation of Sagittarius and therefore near the nucleus of our galaxy the Milky Route, therefore, we can observe in her a great amount of weak stars, stellar and globular clusters.
Telescopium limits the north with the constellations of Sagittarius and Corona Australis, to the east with Ara, the south with Pavus and the west with the constellation of Indus.
Star Tales – Telescopium (219 words)
Lacaille originally depicted Telescopium as extending northwards between Sagittarius and Scorpius, as shown on the accompanying map by Bode, but modern astronomers have cut off the top of the telescope’s tube and mounting so that it is now restricted to the area of sky south of Sagittarius and Corona Australis.
As a result, Lacaille’s Beta Telescopii, positioned in the pulley at the top of the mast, is now Eta Sagittarii, Gamma Telescopii, in the upper part of the refractor’s tube, is G Scorpii, and Lacaille’s Theta Telescopii, which marked the telescope’s objective lens, is humble 45 Ophiuchi (also known as d Ophiuchi).
Telescopium, shown under the name Tubus Astronomicus in the Uranographia of Johann Bode, was envisaged as a long-tubed refractor operated by ropes and pulleys.
