It's been a while since I updated this mod, but having gotten back into New Vegas recently and trying all the newest graphical mods, I found that my old Enhanced Night Sky mod from Fallout 3 was far too saturated and colorful for the more realistic palette in mods like Nevada Skies, URWL, Custom Lighting Overlay, etc. So I've reduced the saturation by about half, fixed a few of the noticably larger stars that stuck out, and released version 0.2 - just in case anyone else was interested in a similar update (should also work well in Fallout 3.)
Thus far I've only tried it out with Nevada Skies URWLified with Custom Lighting Overlay, but I can release other variations in saturation levels if there's a request for it. Let me know, and enjoy!
