This issue has been around from the beginning, but I've just got around to finding a fix. Whenever ENB is enabled you have this gradient ring that progresses from the horizon up to a circle to the center of the sky when looking up. It's very noticeable on clear nights. Only happens with ENB enabled so I'm not sure if anyone has found a fix or a setting in the ENB ini files that will keep this from happening? Below is a vanilla and ENB enabled screen shot.
