It is very dark... in space...

Hmm ... how about making an outline for the currently visible area, then? Mayhap a bright blue one, since that appears to be a somewhat visible colour. I presume it to be somewhat possible to do (well, possible it is, it's the feasibility of it that might or might not be an issue) and that should be enough to get rid of PvK's problem.

I'll add my 2 cents. Yes, the seen area is dark, so much so it's difficult to find discovered planets. Even the discovered area seems dark. Funny, I was playing the demo a few days ago and I don't recall this problem.

The new High Contrast Unexplored option in version 1.20 seems to solve this for me. Thanks!

(Actually, I should re-test this in a brighter room, to make sure.)

Ok, it's still a bit subtle when there's sun outside, but it's a big improvement.
