Hidden Carina Nebula  is one of the highest resolution custom skies out there! With fantastic colors and a hidden view this vista really comes to life! Looking for a scifi theme sky? Look no further! This one will really do the job for you!

 

Note: Requires Optifine! Also, recent changes in Optifine break previous versions of custom skies. My universal pack addresses this issue and will work with any version of Optifine.
