SH commander question

[Enfilade]

From memory, I decreased the water fog level (using SH3 Commander) to 12 or 13. One question though: does this have any impact on making the night sky darker? In my current patrol, even with the lights out in my home office, I have a tough time making out targets at night... the sky just seems a lot darker than in previous patrols. But then maybe it's old age......
