Saturn in Orbiter - Outer Planets
This is Saturn in Orbiter but with the level 7 textures from the "Outer Planets" add-on by VF2_Rolf (Rolf Keibel) and others. The ring texture is more detailed. I believe this add-on is based on 2004 Cassini imagery, but I'm not sure. This add-on also supports a simple moving cloud layer which you can observe by accelerating time in Orbiter.
