galaxy nebula space background purple blue stars
Prompt
Photorealistic abstract galaxy-nebula background with a luminous circular cluster of fine white radial filaments resembling delicate cosmic dust threads, each node glowing like a tiny star. Center the airy spherical structure slightly off-center, filling most of the frame, with bright pinpoints connected by wispy hairlike lines and a soft milky halo around the edges. Behind it, create a richly blurred deep-space texture of purple, cobalt blue, magenta, crimson, and warm amber clouds, with subtle star specks and smooth bokeh depth. Dreamy, ethereal, calm mood; high detail in the white filaments, soft focus in the background. Shot as a macro/astrophotography hybrid on a 100mm lens, f/2.8, shallow depth of field, clean commercial stock style.
