Seven-foot telescope made by William Herschel

Seven-foot telescope made by William Herschel
This is William Herschel’s own telescope. It may be the one he used in his back garden in the spring of 1781 to study what appeared to be a comet. Repeated observation revealed it was a new planet – the first such discovery in written history. Today we call this planet Uranus.
