| Comment : | Uranus, even if it could be seen already in ancient times it wasn't classified as a planet until 1781 when William Herschel observed it. When I took the photograph it was only 20 degrees above the horizon. And only a 300 mm camera lens was used. The above photo is a crop around the planet, here is the full resolution photo and it's plate solved: Uranus, open in a new window. |
