Summary
| Description |
English:
Model of Telescope with which
William Herschel
discovered
Uranus
. In the
Herschel Museum of Astronomy
in
Bath
. The secret of Herschel's success as an observer was the power and magnification of his telescopes. This seven foot long, six inch diameter, ƒ14 reflector was particularly favoured. Its main mirror at the bottom of the tube and the secondary mirror near the top in front of the ocular were made of
speculum metal
. It was with a seven foot telescope that Herschel made the discovery of the planet Uranus in 1781
