Uranus and 4 of its large moons are visible in this image.
Uranus does not normally display any significant surface features due to its small apparent size (4.5 arc seconds) and low contrast, but at least the limb darkening can be seen.
At magnitude 6 Uranus is just barely visible with the naked eye under dark skies, and the moons in this image have magnitudes from 14.0 (Titania) to 15.1 (Umbriel) so they are even fainter than Pluto.
