Dang, PNGs can take a long time to load when you're on a slower connection.
I just came back from an exploration jaunt out through the Elysian Shore, where I discovered HEGEIA WZ-R B32-0. The second planet in this system is a Class 1 Gas Giant with a huge ring system. The A-ring I was able to map, but the B-ring was so far out from the planet that it was unreachable by map probes. This B-ring begins around 2.5ls out, beyond this planet's moon 'C', and extends out close to 5.0ls in total.
