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

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.
