The SDAA has nearly 600 members with varied astronomy backgrounds. Some new members are experienced amateur astronomers ready to set up their scopes at Tierra del Sol, while others are just starting. All members receive an informative monthly newsletter. As an added benefit, subscription to Sky & Telescope and Astronomy magazines are available to members at substantial discounts.
The Club has resources for new members wishing to learn the night sky. Loaner telescopes are available for members without a scope. Several reflectors and refractors are stored at the Tierra del Sol club observatory.
