About Us

We are an astronomy club.

Established in 1965, the Amateur Observers’ Society of New York (“AOSNY”) was created as a means for astronomy enthusiasts of all ages to meet together. Amateur Astronomy is about helping others, learning, doing, and having fun! Our organization has several observing options for the general public, including a 14-inch diameter Schmidt-Cassegrain telescope, housed at our Sue Rose Observatory at the Custer Observatory facility in Southold, NY. We are there almost every clear Saturday night, employing Electronically Assisted Astronomy equipment to comply with social distancing mandates.

Our mission is to bring Long Island astronomy to the public and provide astronomy resources to members. This expresses our commitment not only to serve our members, but also to educate and inspire the public.

Reach for the Universe!

Our activities have grown with our membership. In addition to sponsoring numerous Long Island astronomy activities, we are actively involved with reducing the light pollution problem on the Island and throughout the state. With members owning telescopes of all types and sizes we are more than eager to help with any questions you may have about sky observation, celestial photography, telescope purchasing or anything related to your astronomical interests. We invite you to join us in these events and at our monthly meetings in order to learn about and share our enthusiasm for celestial observation.

Would you like to take a peek through one of our scopes? No problem!

We enjoy being an active Long Island astronomy club with lots to do and participate in, and it is not necessary to own any equipment to join. Come enjoy the wonderful nighttime sky and daytime activities with us. When you join, for a small annual membership fee of $25 or only $30 for the household, you and your family can be a part of the AOSNY family and enjoy more than just the heavens above:
