galaxy nebula space background purple blue stars
Prompt
Photorealistic wide horizontal background looking upward through a dense, unbranded woodland canopy at night, with black silhouetted oak-like branches stretching diagonally from left to right and leafy edges framing the top and bottom. Behind the trees, a vivid celestial nebula fills the sky with soft purple, deep blue, teal, turquoise, amber, and rose clouds, scattered with countless tiny white stars and a few brighter star clusters. Natural low-light mood, dreamy and quiet, with high contrast between crisp dark branch silhouettes and luminous cosmic haze. Balanced composition with the main branch crossing the center and open star fields on both sides, shot as if on a 24mm wide-angle lens, f/4, deep focus, clean fine detail.
