    Description
    Two charts tracing the path of a comet, using fixed stars.

    Figure 3 and 4 from the paper Account of a comet by William Herschel, 1781. Published in the Philosophical Transactions of the Royal Society, volume 71, 492-501, 1781.

    Accompanying inscription ‘Angle of position of the Comet with regard to the parallel of declination of the same telescopic fixt stars measured by a micrometer of which I have given the description, and a magnifying power of 278.

    William Herschel was the first to discover an entirely new planet, Uranus, using a telescope. He initially believed that the object was a comet but further evidence convinced him that this must be a planetary body. The discovery was truly sensational and made Herschel internationally famous. He named the new world Georgium Sidus, after his patron King George III.

    William Herschel (1738-1822) was a British astronomer, he was elected a Fellow of the Royal Society in 1781.
