Seven-foot telescope made by William Herschel
Image number: e2009.8.1_0005
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.
