The Tatacoa Desert is not a true desert but a tropical dry forest, offering a unique atmospheric stability for astronomical observation.
Because of its position at 3 degrees North latitude, observers can view the entirety of both the northern and southern celestial spheres throughout the year.
The observatory utilizes manual and motorized telescopes to track Earth's rotation during observation sessions.
The facility is situated in a region once covered by an ancient sea, resulting in the surrounding distinctive ochre and grey eroded landscape.
Astrosur Uno focuses on naked-eye constellation interpretation combined with high-magnification optical lens observation.
Astronomical Observatory Astrosur Uno is a private stargazing facility located in the heart of the Tatacoa Desert, a tropical dry forest ecosystem. The site leverages the area's extremely low light pollution and arid climate to provide high-clarity views of the equatorial night sky. Visitors observe celestial bodies through professional-grade telescopes positioned directly on the desert floor. The observatory is run by local astronomers who provide educational narrations on constellations, planets, and deep-sky objects. Its location near the equator allows for simultaneous viewing of stars from both the Northern and Southern celestial hemispheres.

Bring a red-light flashlight to navigate the desert floor without ruining your night vision.
Wear long sleeves and trousers to protect against mosquitoes and local desert insects.
Carry extra layers, as desert temperatures drop significantly once the sun sets.
Do not attempt to walk to the site from the town center at night due to limited infrastructure and challenging, unlit terrain.
Avoid using white-light flashlights or phone screens during observation; remain quiet during guided sessions to ensure a meditative environment.
