Telescopium Herschelii, Herschel's telescope:

Created by the Austrian astronomer and priest Abbe Maximilian Hell in 1781. This constellation was made to honor the famous English astronomer Sir William Herschel. The constellation was constructed out of stars that were once part of Gemini, the twins, and Auriga, the charioteer. Telescopium Herschelli first appeared in print in the star atlases of Johann Ehlert Bode (above image). It no longer is considered an official constellation and is largely ignored by modern astronomers.
