An ancient, mystical observatory perched atop a jagged mountain peak under a swirling nebula. The architecture is a blend of gothic stone and intricate brass clockwork mechanisms, with giant rotating gears turning slowly. Through the open dome, a massive, glowing celestial sphere hangs in the sky, illuminating the room with ethereal blue light. Dust motes dance in the light beams. Hyper-realistic, 8k resolution, cinematic lighting, detailed textures of stone and metal, wide-angle lens, fantasy concept art style.
