These night photographs were captured at Cabo San Juan Lighthouse in Fajardo, Puerto Rico — one of the most scenic historic lighthouses in the Caribbean. Perched above the Atlantic Ocean, the lighthouse provides a dramatic foreground for wide-field astrophotography, combining human history with the natural night sky.
Under dark coastal skies, I photographed the Milky Way region, the Andromeda Galaxy, and winter constellations such as Orion, using a Canon 60Da and a wide-angle lens. The constant ocean wind, salt air, and rotating lighthouse beam made these exposures both challenging and rewarding.

| LightHouse Night Sky Astrophotography Puerto Rico — rotating lighthouse beam visible cutting across the sky during long exposure |
The bright diagonal streak visible across the sky is the rotating lighthouse beam, recorded during a long exposure. Unlike aircraft or satellites, the beam produces a broad, continuous band of light that sweeps across the stars as the lighthouse rotates. This effect is especially prominent in coastal astrophotography and cannot be avoided when working close to active navigation lights.

All images were captured during the same Puerto Rico trip, exploring how different celestial targets — from nearby constellations to deep-sky objects like Andromeda — interact with a fixed terrestrial foreground. Lighthouses offer a unique astrophotography subject, symbolizing navigation and light beneath an ancient sky.
