The ChesMont Astronomical Society (CAS) has operated in Chester County and Montgomery County areas in Pennsylvania since 1986. We are dedicated to observing the night sky and educating the public about the wonders of the universe through outreach events.
We meet monthly, on the Sunday evening closest to the full moon, at 7pm at the Crow’s Nest Preserve (see map) in Elverson, Pennsylvania.
