The asteroid belt is being seen as a "ring" in this particular case, and the first planet is close to its outermost edge.First off, many thanks for your wonderful tool! (that's from a dedicated hater of 3rd party tools)
I've just found an interesting bug, that you might want to investigate. On system entry I got this message form passive scanning (no FSS at this point in time):
2020-02-24 17:36:29 - Qiedau HF-Y c17-3 A 1 - Landable - Close ring proximity - Orbit: 1.884.781km, Radius: 3119km, Distance from ring: 26.081km
The only planet in system with a ring is the A9 instead. I can't imagine the app would know about this planet at this point and marking the A1 with "close ring proximity" is plain wrong. Any ideas what's going on here?
This came up once before and was determined to be an odd quirk that the single concerned user at the time was willing to accept as still a noteworthy occurrence even though it was not likely to be that visually interesting. Though it's possible (but unlikely) that a belt cluster might be close enough to the planet to allow for some slightly different screenshots.
I'm still undecided on whether to filter these out or not.
