Victorian Copper Observatory Dome Silhouetted Beneath Comet

Full prompt

Architectural night photograph composed in a 3:4 aspect ratio, featuring the verdigris copper dome of a historic nineteenth-century university observatory resting upon a tranquil hill. The shutter slit is rotated open, revealing the polished brass barrel of a classic refractor telescope aimed skyward from the lower half of the frame. High in the dark indigo firmament above the neoclassical masonry, a brilliant comet shines with exceptional clarity. Its dense nucleus radiates a crystalline white gleam while the expansive gossamer tail drifts upward toward Cassiopeia. Warm architectural light gently washes over the weathered stone base, while deep velvety sky provides ample breathing room across the upper portrait field for an elegant editorial cover.
