I am affiliated with the following groups in the Tucson, AZ area:

Back in Connecticut I frequently did events with the following astronomy clubs and organizations:
Westport Astronomical Society - WAS holds public nights normally once a week (currently once a month due to COVID concerns) and does frequent appearances at science events throughout Fairfield County. The WAS campus is home to a 14" EdgeHD and a 25" Obsession Dob, and will soon host a robotic telescope or two. They also have a fantastic free lecture series every month.
Westchester Amateur Astronomers - WAA also holds free public lectures once a month, and has one of the most well-acclaimed newsletters of any astronomy club out there. WAA membership comes with the benefit of being able to access Ward Pound Ridge Reservation for private observing - the same location where public star parties are held roughly once a month.
Litchfield Hills Amateur Astronomy Club - LHAAC is a small club, but it's got the most well-situated observatory in Connecticut - with skies good enough to see the Milky Way, M31 and M33 with the naked eye easily. The Hoffleitt Observatory has 14" and 12" Meade LX200 scopes. LHAAC's public nights are roughly once a month at White Memorial Conservation Center, which is also freely accessible to the public. LHAAC is also one of few astronomy clubs to have its own Discord server.
Mid-Hudson Astronomical Association - MHAA does frequent online events as well as monthly star parties at Lake Taghkanic State Park.
Boothe Memorial Astronomical Society - BMAS has bi-monthly meetings/public nights at its observatory or in the field in front of it.
My scopes are available for private star parties, birthday parties, etc. - please email or call me for pricing and more information.
