Mt Tam Astronomy

Welcome to the Mt. Tam Astronomy Program, designed to give people of all ages and backgrounds a better understanding of our universe by learning of current theories and discoveries. It's organized by Mt Tam Astronomy Program, San Francisco Amateur Astronomers, and Wonderfest, funded by your donations and FMT.

Evening programs are held each Saturday between new and first quarter moon from April to October. A talk by a professional astronomer, physicist, or space scientist begins near the end of twilight and lasts about 45 min, typically with beautiful images on a large screen. Questions are welcomed at the end.

Immediately following, the audience is invited to remain for a brief Night Sky Tour by Urban Astronomer, highlighting prominent constellations, stars and planets visible in the nighttime sky.

The audience is then invited to Rock Spring parking area to look through telescopes provided by San Francisco Amateur Astronomers. The observing “star party” lasts from 1 to 1½ hours.
