Nebula Over Canyon: Photorealistic Vista

Photorealistic landscape of a deep sandstone canyon at dusk, with towering red-orange rock walls carved into dramatic formations. In the open sky above, a luminous nebula unfurls ribbons of pink, purple, blue and teal, with bright star clusters and wispy gas clouds. The nebula's glow bathes the canyon in surreal light, illuminating rock textures and mineral veins. A narrow, reflective pool runs along the canyon floor, mirroring the celestial spectacle. Include ultra-realistic details: realistic atmospheric perspective, dust motes in the air, HDR-quality lighting, and a wide-angle composition that emphasizes depth.
