This add-on adds a 4K texture for Uranus, based in part on Voyager 2 coverage in 1986. It also adds the faint outer rings Mu and Nu, discovered by Hubble observations between 2003-2005, as well as the broad, inner and also faint ring Zeta/1986U2R, first seen by Voyager. Lastly, it includes five additional "Locations" in the rings.
