TL;DR: If nothing else, I need help finding a way to remove the dust, or haze, surrounding Moho. I believe this would fix this issue, but cannot for the life of me find out how to do it.
More details:
At wit's end with visual glitch surrounding Moho. I believe everyone should be experiencing this. Black sky, or noticeable border between black/dark and lighter sky. Screenshots below. The effect can be more or less noticeable depending on how you tweak some settings within TUFX and PlanetShine.
I believe what we're looking at has something to do with the dust or haze surrounding Moho. At certain points, it looks like there's some distance culling in the mix, as the effect enlarges or shrinks in a circle as you move the camera around. Could not reproduce on video.
The effect diminishes and disappears as one goes down to the planet's surface or up into high orbit.
Attempted fixes (using CKAN, so dependencies are managed automagically):

Please, anyone, if you can at least help me find the effect, shader config, or texture of the haze surrounding moho (in orbit, not on the ground), you have my deepest thanks. I have already spent way too many hours trying to hunt this bug down. If anyone can hop by Moho with AVP installed and confirm whether they observe the issue or not, it would also be immensely helpful. Especially if, in case you don't, you can share which mods you have installed and any out of the ordinary configs.
Note that the effect surrounds the planet. If you're looking at it straight down, all is good:
