StellariumCatalog is a mod that lets you display constellations in the sky. It includes constellations from dozens of cultures. Constellation data is sourced from Stellarium. The skybox in KSA is rotated incorrectly, so the constellations in this mod are rotated to match.
See the 'How to install' instructions on the GitHub page for more detailed instructions.
