galaxy nebula space background purple blue stars
Prompt
Photorealistic panoramic deep-space background filled edge to edge with layered nebula clouds, dense star fields, and glowing cosmic dust, designed as an abstract texture for stock use. Compose with sweeping vapor-like formations drifting diagonally across a dark void, one soft bright star cluster slightly left of center, scattered pinprick stars throughout, and subtle luminous knots embedded in the gas. Lighting feels celestial and ethereal, with gentle internal glow rather than harsh contrast. Color palette of deep indigo, violet, electric blue, magenta, smoky cream, and hints of warm copper. High-detail astrophotography style, ultra-wide composition, simulated long-exposure telescope capture, crisp stars against softly diffused nebula depth.
