Note that this pack requires optifine to work. I have tested it and it works in versions 1.7 - 1.12, it will say "may be outdated." Just ignore and use, it still works.
Also note, your view distance "must" be at least "8" in order to see the night sky.
Here are the download links for the resource packs. Enjoy!:
