For version 1.0, the file needs to be named end_sky.png instead of custom_end_sky.png It isn't necessary, but if you don't add the file, the end could look like the picture above. Unless you are using the resource pack that I made, you need the file assets/minecraft/textures/environment/custom_end_sky.png to be a custom sky image from a custom sky resource pack, which you can find in the assets/minecraft/optifine/sky/world0 folder. I made a resource pack here that uses the custom sky without having to edit the resource pack:

Use with a resource pack! It won't work without one that adds a custom end sky.

Also, there are different instruction on how to prepare the resource pack for version 1.0. You can find version 1.0 under the 'files' tab above. Version 1.1 doesn't work with optifine, so if you want to use it with optifine, you need either version 1.2 or version 1.0 of the mod. Version 1.2 works with optifine, though version 1.3 doesn't work with current versions of optifine and forge. Just using the Hidden Carina Nebula texture pack isn't enough, you need to find the texture and use it to replace the end sky texture using the instructions near the bottom of the page. Big credit to them for making this amazing texture pack for the overworld. You can install Sodium to workaround this issue.Texture taken from Hidden Carina Nebula.
