Winter Observatory at Serra da Estrela, Guarda

Ultra-detailed photorealistic winter landscape in Serra da Estrela, the highest massif in mainland Portugal, located in the Guarda district. Snow blankets pine forests and jagged granite slopes. A small astronomical observatory sits on a snowy ridge, featuring white hemispherical domes and a glass-walled annex with faint interior lighting and visible telescope tubes. A snow-covered trail winds through the foreground, dotted with footprints and a weathered stone wall. The sky is blue-hour blue, with a gradient to deep indigo and a scattering of stars, with a subtle Milky Way arc. Distant valleys are softened by mist, and distant peaks glow pink from alpenglow. Crisp air, high-contrast textures of snow, metal domes, and glass, cinematic lighting, wide-angle composition.
