10 HDRI 8K Galaxy and Nebula Backgrounds

10 very different galaxy and nebula panoramas for sci-fi skies, space scenes and lighting. Each one is a full 360 degree equirectangular image at 8192 x 4096 in 32-bit HDR.

Every panorama has its own look: violet and teal star clouds, an orange and gold nebula field, pale grey dust, silver star clusters, a soft pink glow, a purple haze, swirling blue and orange filaments, and a green and cream cloud structure. That range makes it easy to give each location or level its own sky.

Good for:
- Skyboxes and sky domes in sci-fi games
- Reflections and image-based lighting
- Cinematic space shots and VFX backgrounds
- VR and 360 degree environments

What's in the download:
- 10 unique panoramas in 32-bit Radiance .HDR format, 8192 x 4096 (2:1)
- A contact sheet with numbers that match the file names
- A short README with setup notes for Blender, Unreal Engine and Unity

Every file was checked for bad pixels and the left and right edges join cleanly. These are true high dynamic range files with very bright star cores: peak values run from about 165 to several million, with the highest in file 07. Start with a low intensity, and clamp the brightest values if your renderer shows sparkles.
