Got a question: Are Neptune's rings equatorial? Reason I ask is after looking at the image again it looks like one of the polar areas is sunlit & the other isn't, like Uranus. Neptune's axial tilt is around 28 deg, so I'm betting that this is a viewing geometry thing...but can't quite figure it out.

Yes they are pretty much equatorial, however, Joseph Burns has noted there is some inclination in the outer edge, apparently related to the effects of the inclined orbit of Triton.

Voyager 2 went right over the north pole so on its way out it took a southward plunge. you are looking at the south pole from behind. Something like some of the Cassini views of saturn. -------------------- Dr. Paul Schenk, Lunar and Planetary Institute, Houston TX
