galaxy space stars nebula dark
Prompt
Photorealistic deep-sky astrophotography background of a vast emission nebula suspended in black space, centered in a square frame. A softly glowing blue-gray core fades into smoky translucent gas, surrounded by uneven rust-orange and warm copper outer clouds with darker dust lanes winding through the structure. Thousands of tiny white stars are scattered across the deep black background, with a few subtle brighter points for scale. Natural celestial illumination, quiet mysterious mood, high contrast but restrained, palette of midnight black, icy blue, ash gray, amber, and burnt orange. Composition feels expansive and immersive, no horizon or foreground, captured as if through a large telescope with long exposure, crisp star detail and gentle nebulous depth.
