this is simply a texture mod mainly affecting the skies, featuring:

• binary suns - there's two of them now, a big blue one and a small orange one
• a volcanically active moon - if you look closely you might see the volcanoes, especially during a new moon
• a new night sky - a view from within the Small Magellanic Cloud, with views of a nebula, the Large Magellanic Cloud, and the Milky Way
• a darker, bluer daytime sky
• bluer, more vibrant water

this mod is available in three versions, with different night skybox texture resolutions
1k (1024x1024) available right here on this page
2k (2048x2048) available on my website due to its size
4k (4096x4096) available on my website due to its size

this mod also pairs well with Volumetric Shading ReUpdated, though it overrides my sky color changes

all textures except the sun (which i made myself by hand) were exported from SpaceEngine Pro

this mod should remain compatible with all future game versions, being nothing more than a simple texture replacement
