Finding Uranus and Neptune

Uranus is the first planet to be ‘discovered‘. It was discovered, only after the advent of the telescope,  by British astronomer William Herschel on March 13, 1781,  completely by chance. It was later realized that the planet is actually bright enough to be seen with the naked eyes. May that be,  it is quite easy to locate the planet using a pair of binoculars.
