We welcome anyone interested in astronomy. Membership entitles you to attend monthly general meetings, special club events, and observing sessions at our dark sky observing site. You can also take part in our club’s participation in public and private star parties. We keep members informed about all activities via the CAS website and email reminders.

Membership types include "Individual," "Household" for two adults from the same address, "Junior" for those under 18 or who are college students, and "Sponsoring" for those wishing to help support the Society (a portion of which may be tax-deductible.)

Current and new members now have the option of paying dues by using a credit card (via PayPal). A PayPal account is not required. This convenient payment method is a free, secure service.
