Corona Borealis Mirrored in a Still Alpine Tarn

Full prompt

A panoramic horizontal 16:9 landscape photograph captures a tranquil midnight scene beside a mirror-like glacial tarn in the Canadian Rocky Mountains. Jagged granite spires and dark subalpine fir silhouettes stretch across the horizontal midground, their rocky contours perfectly mirrored in the glassy, undisturbed water of the lower half. In the dark indigo sky above the central mountain pass, the delicate semicircular jewel arc of Corona Borealis—the Northern Crown—shines with crystalline brilliance, anchored by central Alphecca glowing like a pale diamond. The wide aspect ratio provides expansive lateral scale, balancing the rugged wilderness horizon with the pristine stellar arc and its twin water reflection under an undisturbed, dust-free alpine nocturne.
