“Long Island's oldest public observatory”
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.
It's a great place to go see the night sky on a Saturday night. We could see the moon, planets, and things we never knew existed. Watch the weather though. It's no good to go on a cloudy night.
