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 always welcome. If it is clear, bring your telescope!
