| Meetings |
|
|
The CAS meets on the second Saturday (8 PM) of each month at historic Perkins Observatory near Delaware, Ohio. Visitors are welcomed to attend. Occasionally our meetings are held at a different location, so it is a good idea to confirm the time and place prior to departure. Perkins Observatory is located just off of Route 23 north of Columbus OH (about 10 miles north of I-270) and just south of Delaware OH (about a mile south of where 315 intersects 23).

| Public Star Parties and Events |
|
|
The CAS provides assistance each weekend with the public educational programs held at Perkins Observatory. CAS volunteers help in many ways on these busy nights including setting up their personal telescopes on the lawn, providing tours of the facility, and operating the 32" Schottland telescope for the visitors. The CAS periodically conducts public-oriented exhibitions away from Perkins. Many people get their first look through a telescope at these events. The programs also allow the public to discover more about amateur astronomy, including the wide variety of equipment that is used. |
