If you’re curious about the night sky, or already exploring it, CCAS is here to support you.
We’ve been sharing astronomy across San Luis Obispo County since 1979, welcoming everyone from first-time stargazers to experienced observers, students, families, and professionals.
Membership is simple, affordable, and gives you a community of people to observe, learn, and explore with.
