Members come from all backgrounds and have a broad spectrum of experience with astronomy, from absolute beginners through to professional or semi-professional practitioners.

If you are new to astronomy, you will find our Summer Star Parties useful, with public and members-only viewing ‘above the fog’ on Mt Tamalpais in Marin.

Those who are experienced and are looking for fellow experts to challenge you or share best practice, members’ nights and Astronomy Lectures are for you.
