starry night sky with single bright star
Prompt
Photorealistic vertical background of a vast starry night sky, filled edge to edge with countless tiny white and pale blue stars scattered naturally across a deep navy-to-black atmosphere. Include one noticeably brighter star positioned slightly off-center in the lower right quadrant, crisp and luminous but not exaggerated, with a subtle cool glow. No horizon, land, clouds, moon, people, objects, text, or landmarks, just open cosmic darkness with a faint teal-blue gradient near the lower portion. Calm, quiet, expansive mood, cool midnight color palette of indigo, blue-black, soft cyan, and clean white. Minimal composition with generous negative space, shot as an astrophotography-style long exposure on a wide-angle lens, 24mm, f/2.8, ISO 1600, clean natural grain and sharp star points.
Negative Prompt
