William LassellDied 5 Oct 1880 at age 81 (born 18 Jun 1799).English astronomer who was an amateur with enough wealth to set up an observatory at Starfield, near Liverpool. England, He built his own 24" diameter telescope, and devised steam-driven equipment for grinding an polishing the speculum metal mirror. This telescope was the first of its size to be mounted “equitorially”to allow easy tracking of the stars. He discovered Triton, a moon of Neptune, and Ariel and Umbriel, satellites of Uranus. Later, Lassell built a 48" diameter telescope with the same design and took it to Malta for observations with clearer skies. |
