Discovery of Uranus
When William Herschel was cataloging double stars in the constellation of Gemini that astronomers might determine, by parallax, their distances from Earth, he discovered an object without a tail brighter and larger than a star that appeared as a disk and grew in diameter as he zoomed in on it, which could not be a star because stars always appear as points of light. So Herschel wrote to other astronomers, and Anders Lexell calculated that its orbit was nearly circular, meaning it had to be a planet.
Herschel made more than four hundred telescopes, including a reflecting telescope with a forty-nine-and-a-half-inch-diameter mirror and a forty-foot focal length. The telescope with which he discovered Uranus he made of wood with an altazimuth mount and a reflecting mirror of speculum that he had made and polished himself. This telescope had a diameter of six and a half inches and a focal length of seven feet.
If I cannot peer with a better instrument which for a better reason I cannot find then bless my intuition which seems to be blunted before it can cut.
