I know that, I just wanna know where can I find this first version. Because as far as I can see, the 4 curseforge downloads all contain the exact same files both in the environment folder and in the mcpatcher folder, that is, I cannot find any extra star images in any of them. I also don't know if you're talking about the environment folder, or the mcpatcher folder. Both contain some sky images.
Whichever is the first version will have it.
