Telescopium Herschelii

Telescopium Herschelii (Latin for Herschel's telescope), also formerly known as Tubus Hershelli Major, is a former constellation in the northern celestial hemisphere.

It was one of two constellations created by Maximilian Hell in 1789 to honour the famous English astronomer Sir William Herschel's discovery of the planet Uranus.

[1] Named Tubus Hershelli Major by Hell, it was located in the constellation Auriga near the border to Lynx and Gemini and depicted Herschel's 20-ft-long telescope.

[1] Located 420 ± 20 light-years distant from earth,[3] it is an orange giant of spectral type K3III.,[4] although the magnitude 3.60 star θ Geminorum is brighter.

[6] This is the list of notable stars in the obsolete constellation Telescopium Herschelii, sorted by decreasing brightness.
