Overview:
Masser and Secunda now glow. The fuller the moon, the brighter the glow. Glow is more apparent behind clouds and/or near the horizon.
This is a script-free mod that works by expanding the texture dimensions of the moons to make room for a glow overlay. Normally this would result in smaller moons, but the esp file is used to restore the moons back to their original sizes. The esp file can be easily merged into other plugins to free up a slot if needed.
