|Jupiter, the Moon, and Venus, lining up in March 2012|
At last week's observing session at the High Line in Manhattan (which occurs every Tuesday night from April to October, weather permitting), WGINY was able to glimpse the rings of Saturn, the crescent phase of Venus, and the binary properties of the star, Castor, among other celestial objects, through the surprisingly high-powered telescopes set up by the "amateur" astronomers. Although membership is encouraged to support the organization, any visitor or passerby is warmly invited by AAA members to partake in observing sessions. If you thought you couldn't see stars in New York City due to ambient light, you'll be shocked by what the AAA can show you, and tell you. I have attended observing sessions in Manhattan and Brooklyn, and have learned so much (including how to best position my own travel scope...) just from a few moments of discussion with the interesting, knowledgeable astronomy-buffs who host these events.
And, if you want even more ways to seek out stars:
Columbia University Astronomy Outreach: lecture and stargazing sessions every other Friday.
College of Staten Island Observatory: public schedule varies.
