Welcome to the Custer Institute
The Custer Institute and Observatory is Long Island's oldest public observatory (est.1927). Open to the public every Saturday evening from dark until midnight, our staff of volunteers will give you a tour of the facilities and the night sky through our powerful telescopes. Custer has frequent lectures, classes,concerts, art exhibits and other special events. Consider our observatory for your next meeting or theme party.

As
the days get cooler, the night comes earlier. However, remembering that
Custer is run by volunteers, despite the time of darkness, Custer will
open at 7pm. Observing from the dome will begin after 8pm. See you then!
