I just got stellarsky today and I noticed after checking my inventory that a giant blue cylinder appeared... seems to be focused on my head.

Also really happy with CelestialSettings.cfg

I edited D:Minimum_Sky_Render_Brightness=0.01
The 0.01 brings the natural night light level down so far it looks like a horror game, and lets you see the beautiful sky without so many distractions.

Ah, figured it out... the problem was with photoptics.

@HypnoPants please close the Issue.
