18 HDRI 8K Celestial Abyss Space Panoramas

18 deep space panoramas with bright central nebulae on dark star backgrounds, for sci-fi skies and lighting. Each one is a full 360 degree equirectangular image at 8192 x 4096 in 32-bit HDR.

The set is built around glowing white cores wrapped in fine gas filaments, with colour moods from pale silver and blue through magenta, violet, emerald and cyan to warm gold star clusters. Several panoramas share a shape in a different colour, which is useful when you want a matching family of skies.

Good for:
- Space and sci-fi games, as skyboxes or sky domes
- Cinematic backgrounds and VFX
- Lighting and reflections on ships and planets
- VR and 360 degree environments
