In 2011, the Cincinnati Astronomical Society (CAS) celebrated its 100th anniversary of serving amateur astronomers from all around the Tri-State. Our centennial marked a long tradition of sharing the wonders of the night sky with the general public, students, teachers and scouts of all ages.
In 2021 CAS celebrates its 110th anniversary as an organization dedicated to amateur astronomy. Our members are generous with their time as they volunteer for public outreach at our facility near Cleves, as well as with our partners around the tri-state area. Please see our calendar for a list of events. Your tax-deductible donations allows us to maintain and upgrade our facilities for the purpose of furthering amateur astronomy in the Cincinnati area, as well as offer programs to the general public.
Donate online. It’s fast, easy and secure.
