A nebula drifts through an indigo night sky, seen from a mountaintop observatory; the vivid colors of the cosmic dust swirl and bloom in high-definition, hyper-detailed flux realism, with sharp, precise linework and a palette that blends deep blues, purples, and vibrant pinks, all rendered with a hyper-realistic, almost photographic finish that emphasizes the ethereal beauty of the cosmos, set against the dark, textured silhouette of the observatory dome.
