Mount Tamalpais

Friends of Mt Tam_logo
This is an educational program designed to give the general public and students of all ages and background a better understanding of our universe by hearing about current theories and discoveries followed by an opportunity to observe through telescopes.

Evening programs are held each Saturday between the new and first quarter moon from April through October. A talk by a professional astronomer, physicist, or space scientist begins in the Mountain Theater near the end of twilight and lasts about 45 minutes. These presentations are typically enhanced by beautiful images projected on a large screen. The audience is invited to ask questions at the end.

Immediately following each month’s lecture, the audience is invited to remain in the Mountain Theater for a brief Night Sky Tour by the Urban Astronomer, Paul Salazar, highlighting the prominent constellations, stars and planets visible in the night time sky, before enjoying the observing session (star party) conducted by the San Francisco Amateur Astronomers in the Rock Springs parking lot.

Following the lecture, audience members are invited to the Rock Spring parking area to view through telescopes provided by members of the San Francisco Amateur Astronomers. The observing session (or “star party”) lasts from 1 to 1 1/2 hours, depending on the seeing conditions and the size of the crowd.
