I am holiday in Bath at the moment. I was looking at the map of the city and I noticed that there was a Herschel Museum of Astronomy. This turned out to be a small house. I dimly knew (once reminded) that Herschel had discovered the Planet Uranus. What I didn't know, was that Herschel was originally a musician in Bath, but as a hobby he started to study astronomy. Then he started to build his own telescopes.
The museum was very small, but it made the discovery of the planet more real. He spent many many hours polishing mirrors.
