Long Island Sights



Custer Institute Review

Taking advantage of some of the darkest night skies on Long Island, this observatory is a prime viewing spot for astronomy buffs and star-deprived urbanites. Atop the barnlike structure is a motorized dome with a telescope you can use to track the heavenly view.
