galaxy space stars nebula dark
Prompt
Photorealistic deep-space background showing a dense galactic star field with a broad vertical river of nebula dust and starlight running from upper left toward lower center, leaving deep black negative space on the right. The cloud structure is layered and textured, with creamy white luminous cores, smoky charcoal voids, warm amber and rusty brown dust lanes, and a few subtle crimson emission glows scattered through the center. Countless tiny stars vary naturally in brightness and size, crisp but not exaggerated. Quiet, vast, mysterious mood, high dynamic range without halos. Vertical composition, no horizon or foreground, shot as tracked astrophotography with a long exposure, 85mm lens feel, f/2.8, fine detail and natural contrast.
