Welcome to the home page of the Columbus Astronomical Society, an organization devoted to the enjoyment of astronomy. Founded at The Ohio State University in 1947, we have been sharing our love of astronomy with Central Ohio at star parties, science fairs, schools, and anything astronomical.

We have monthly meetings and regular activities. Meetings are normally at Perkins Observatory (SR 23, 10 Miles North of I-270 towards Delaware) on the second Saturday of every month (8pm start time). Guests are welcome on regular meeting nights which consist of an astronomical topic . Our regular meeting nights occur every month except August and December which are member meeting nights.  If it is clear, bring your telescope!

The Columbus Astronomical Society has over 200 members with a variety of interests: amateur telescope makers, astrophotographers, observers, telescope specialists, and much more.
