16K Deep Field Skyboxes – 5 HDRI Galaxy Panoramas

Five seamless 16K (16384 x 8192) deep-field space skyboxes for Unity: a grand barred spiral, twin spirals, a galaxy trio, an edge-on knife-edge galaxy and a lone face-on spiral, set in sparse star fields with thousands of faint background galaxies and true black space. Natural high dynamic range and no clutter - realistic deep space instead of busy, stylized starfields.
