Telescopium (Pronounciation:Tele-scope-e-um, Abbrev:Tel, Latin:Telescopii) is a constellation, one of 88 constellations that the night sky is divided into. The sky is not divided up equally between the constellations. Telescopium takes up 251.512 sq. degrees of the night sky which equates to 0.61% of the night sky. The constellation gets its name as it name means The Telescope . It was not one of the original constellations that had been devised by Ptolemy, instead it was created by AbbÃ© Nicolas Louis de Lacaille years later.
Telescopium is not a member of the Zodiac group of twelve constellations that appear when the Sun sets. Telescopium is a southern hemispheric constellation which means it can't be seen easily or at all from the northern hemisphere.
The number of stars that have been catalogued as part of the Hipparcos Star Catalogue from Telescopium is 904. The number of stars that are of magnitude 6.0 or lower in the constellation is 27. The number of stars in the constellation that make up the outline is 6.
There are no deep space objects that were identified by Charles Messier in this constellation. There are no non-Messier deep space objects in this constellation that are covered at present on this site.
The nearest star to Earth is HIP 99701 which is roughly about 20.22 Light Years from the Earth. The nearest star to the Earth with an exoplanet is PZ Telescopii which is about 167.95 Light Years. The furthest star that can be located in the constellation is HIP 97227 which is located about 163082 Light Years away from the Sun. The furthest figure is derived from either the 1997 or 2007 Hipparcos star catalogue parallax figure and it has been known to produce distances that are wrong.
The dimmest star that can be seen in Telescopium with the naked eye is HD 177406. The dim star has an apparent magnitude of 5.95. The dimmest star that a person is able to see with their naked eye is 6.0 magnitude based on the table in the reference. Ref: University of Michigan
The caveat of these stars are that they are catalogued on this site. If you know of a star that is nearer or further then do let me know in the comments and I'll add it to the site. The stars mentioned are from the Hipparcos catalogue or have been added because of their special status.
There is no Greek Legend behind this constellation. It was created by Abbé Nicolas Louis de Lacaille to fill in the voids in the astronomical charts.There are no major meteor showers that radiate from within this constellation.

As there's so many stars in the cosmos, not all the stars are listed here. The site has lots of stars not listed so if your star isn't listed and you know the Henry Draper or Hipparcos ID, type https://www.universeguide.com/star/ then followed by the HIPNNNNNN or HDNNNN where NNNNN is the number part of the name. The stars that I do list have either a traditional name, a bayer or other classification name.
