Well... at least I get to make a record, even if my spaceship might be stuck in an INVISIBLE RING now. I might petition this if I can't get on my own. >_>

LARGEST SEPARATION BETWEEN TWO CONSECUTIVE RINGS
LAGOON SECTOR FW-W D1-73 3 WITH 1,831,429 KM (hope my calculator did not fail me

)
Went out to the approximate coordinates of where the third ring should be, didn't see anything, went closer, did get prox and impact warnings, still didn't see anything, then emergency drop and now whenever I try to get out it will instantly 'too close! dropping' put me back into normal space. Hoping I can get out with repeated FSD activations... otherwise I might be doomed.
EDIT: Got out safely. Few percent of hull and module damage was paid for the mishap. The C ring is apparently invisible.
