Not by eye: Oberon is magnitude 14.1 and sits farthest out from Uranus of the five, so it takes a telescope and a steady night.
How the map draws it
Its surface is a black-and-white mosaic, tinted in a colour chosen from published descriptions · only the southern half was photographed, by Voyager 2 in 1986; the rest is left plain, not guessed · lit as a camera exposed for its own sunlight would show it · seen from far off it is a light at its computed brightness: the glow is how a camera records a point too bright to resolve.
