Architectural photography at night, landscape 3:2: a white observatory dome with a slit opening and warm lit windows sits on a snowy mountain ridge under a dense winter starry sky with the Milky Way arcing overhead; low-angle view with snow-covered pine branches framing the foreground, a stone path with footprints leading up to the observatory, two tiny visitors with lanterns for scale, deep blue night sky, crisp stars, cold moonlight on snow against warm window glow; 24mm wide-angle lens, sharp architectural detail, no text, no watermark, no logo.
