Herschel's Discovery

I learned that William Herschel was not originally an astronomer by trade. He was actually an Organist in the city of Bath. After he had discovered Uranus, he sought to find how planets and stars were made rather than tracking the orbits of comets and planets. I find this significant because Herschel sought information that was different than what other astronomers were studying at the time.

What was the motivation that led to the discovery?

William Herschel was frustrated with the small telescopes he was using. He couldn’t afford larger telescopes, so he built one himself. He was observing a Nebula when he discovered Uranus.

What questions were asked?

How can he see it? What if it is a planet? What are we going to name it? What did his work do for England?
The significance of finding Uranus was that it was the first planet discovered since the beginning of recorded history. Up to that point, it was only believed that Mercury, Venus, Mars, Jupiter and Saturn were the only planets (Earth withstanding because of the Geocentric beliefs of the time period).
