More Realistic Skies: Astrocraft Addon
More Realistic Skies: Astrocraft Addon changes the sky of a world by adding moons, planets and custom axial tilts on top of the Astrocraft mod, which it requires.
What it does
Players who want a more accurate sky can use this addon to set axial tilts, day lengths and sky colors for the bodies visible above them. Astrocraft provides the base planets and moons, and this addon extends them with configurable values rather than fixed ones. Users can edit the axial tilt of each planet, set a minimum and maximum tilt value, and choose a tilt variation period so the tilt changes over time.
The addon also controls day length. Custom day lengths can be paired with custom sky colors so the color of the sky matches the length of the day, and solar day lengths and rotational periods can be set separately. Axial precession is configurable, and the addon lists comets and nodal apsidal precession among its planned features. Installation needs Astrocraft and Cloth Config API. Mod Menu is optional and adds a configuration screen. The mod is published for Fabric and Quilt for game versions 1.20.1 – 1.20.6 and runs on the client only, so servers do not need it.
Key features

Custom day lengths can be set for each body, with sky colors that follow the chosen length.
Configurable precession
Axial precession can be adjusted, giving the planets a more varied motion over time.
