Rochester's Astronomy Club — The Astronomy Section of the Rochester Academy of Science (ASRAS). They are a non-profit organization promoting amateur astronomy and public education throughout the Greater Rochester region. The club has an observatory facility in Ionia, NY (roughly 40 minutes from the City). They hold monthly meethings, that are open to the public, usually the first Friday of every month (meeting locations are usually at RIT or their observatory in Ionia).
ASRAS frequently hosts 'Star Parties' at various parks and other public venues throughout the year. If you need help with that telescope you got over the holidays or want to see that comet that was in the news...this is the group for you. See Also Stargazing
