galaxy nebula space background purple blue stars
Prompt
Photorealistic deep-space background showing a vast star field above a luminous nebula, composed as a square frame with dense pinprick stars scattered across the upper two-thirds and rolling cosmic dust clouds along the lower third. Soft violet and indigo gas fades into midnight blue, with warm rust, amber, and muted magenta dust forming a sculptural central plume. Several brighter stars create subtle natural diffraction glints, while tiny distant stars add depth and scale. The mood is serene, mysterious, and expansive, like a long-exposure astrophotography capture. High detail, natural cosmic contrast, delicate misty textures, shot as if through a deep-space telescope with a long focal length, crisp stars and softly layered nebula haze.
