The Astronomy Connection


TAC is a service for amateur astronomers in the San Francisco bay area. TAC is unique. It is not a traditional astronomy club. It has no dues, officers, by-laws, or other official trappings. . . It is an informal network of those who think they might be, or already are, interested in learning from or joining experienced observers to enjoy each other's knowledge of the sky/equipment and comraderie. TAC's goal is to bring together active observational amateur astronomers, bay area wide, via the Internet where ideas can more easily be exchanged and new friendships made.

TAC is not a formal organization and does not compete with traditional astronomy clubs.  TAC's goals include announcing events offered by bay area astronomy clubs to help increase their memberships and public visibility. There are many great programs offered by existing membership-fee based clubs that TAC will not offer. We encourage you to contact one or more of the many other fine clubs available to serve your needs in ways TAC does not.

CalStar 2013

That was fun last year!  Lets do it again!!

(Details to follow, anyone with edit privs, feel free to jump in!)


New Moon is on the 4th at 5:34pm PDT.


CalStar is a pure observing event, there's no services on site except porta potties and water,  and the dark skies of southern Monterey County, in a dry protected bowl.    We camp in an overflow area of Lake San Antonio South Shore facilities.  No vendors, no public night, no green laser pointers :)
