Not by eye: Enceladus is magnitude 11.7, and so close to bright Saturn and its rings that it is hard to see even through a small telescope.

How the map draws it

Its colours come from infrared, green and ultraviolet pictures, toned down toward what an eye would see · 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.
