Right! I don't think it's "borderline naked eye at all". It's clearly
visible on an average - or even below average -night at IHOP (IceHouse

"yellow" (CSC light pollution map) on an average night.

I call it borderline because some people can see it, and some can't.
Also, to see it naked eye requires reasonably dark conditions. I would
use "borderline" for objects like M31 and other DSOs that are close
enough to visual thresholds that in a given group, some people will
simply not see them, even if they have reasonably normal vision.
