Star Tales – Telescopium Herschelii

There were originally two such constellations, both introduced in 1789 by the Hungarian-born astronomer Maximilian Hell, director of the Vienna Observatory, in commemoration of William Herschel’s discovery of the planet Uranus. Hell first showed them on charts contained in the Ephemerides astronomicae (a yearly almanac) for the year 1790 published by the Vienna Observatory in 1789. The two constellations flanked the area in which the new planet was found. Tubus Herschelii Major, as Hell called it, represented Herschel’s 20-ft-long (6-m) telescope and lay between Gemini and Auriga. Tubus Herschelii Minor, crammed awkwardly between Orion and the head of Taurus, represented Herschel’s 7-ft (2-m) reflector.

Bode reduced the constellations to one in his Uranographia atlas of 1801 under the name Telescopium Herschelii. Bode located this constellation where Hell had placed Tubus Herschelii Major, and he depicted the 7-ft telescope with which Herschel actually made the discovery of Uranus.
