Time Out says
Every Tuesday, this dreamy affair gives you an astronautworthy view of the stars from the high-powered telescopes of the Amateur Astronomers Association. And here we all thought we couldn't gaze at constellations in New York City. Just in case you're worried you'll have no idea what you are looking at, the AAA leads the star-spotting expeditions, pointing out celestial bodies above the park.
