Mount Cuba Astronomical Observatory

Mount Cuba Astronomical Observatory is a research and education site in Greenville, Delaware, that plays a working role in one of astronomy's more unusual global collaborations.

About Mount Cuba Astronomical Observatory

The observatory serves the Delaware Astronomical Society and the University of Delaware, and is a participating site in the Whole Earth Telescope, a worldwide network of observatories that coordinates observations to watch variable stars around the clock without gaps caused by daylight.

Telescopes & research

Instruments on site include a 24-inch Tinsley telescope, a 4-inch telescope dating to 1887, a 1.3-metre remote research telescope, and a 0.6-metre telescope. A Sunquest sundial near the parking lot, designed and machined by Richard L. Schmoyer, automatically corrects for the equation of time using an analemma-inspired gnomon. The observatory also has a planetarium and lecture room, and works with local schools, the Mount Cuba Astronomy Group, and youth organizations to bring astronomy to the wider public.

The observatory is located in Greenville, Delaware, in the North America region of the United States.

The Whole Earth Telescope network exists to watch stars continuously by tracking precise coordinates as the Earth turns, the same coordinates that anchor a Star Register named star. Name a star and find it in the catalogue to bring along on your next visit.
