The Galápagos Islands offer a rare opportunity to photograph the southern night sky from an equatorial location. In this image, the sky is filled with southern-hemisphere highlights rarely visible from mid-northern latitudes.
Prominently visible are Alpha Centauri — the closest stellar system to our Solar System — the distinctive Crux (Southern Cross) constellation, and the faint glow of the South Celestial Pole. A palm tree in the foreground provides a natural tropical frame, emphasizing the unique location and latitude.

The South Celestial Pole in this image is located using two independent geometric methods. The first method uses the Crux (Southern Cross) constellation: a line extended along the long axis of Crux points toward the south celestial pole.
The second method uses Alpha Centauri and Beta Centauri. By drawing an imaginary line connecting these two bright stars and then constructing a perpendicular line through the midpoint between them, this perpendicular also points toward the south celestial pole.
When both constructions are applied to the same image, the Crux axis line and the Centauri perpendicular intersect very close to the south celestial pole. The annotated image above shows this intersection clearly.

From this image, the south celestial pole appears very close to the horizon. Because Isabela Island lies on the equator, this photograph captures a true equatorial sky — a rare vantage point where the geometry of Earth and the celestial sphere becomes visually apparent.
