Welcome to the Tri-Valley Stargazers Astronomy Club's web site. There is a lot
of information here on the many activities of the Tri-Valley Stargazers
(TVS). Learn why you should join the club to get the most out of your
amateur astronomy hobby in the east San Francisco Bay Area.
The Latest News & Upcoming Events
Dr. Kenneth Lum will give us the next talk in his series about the
history of the telescope. The tentative title of the talk is The Evolution of the
. Watch this space for more details!
H2O Open House
Our next open house is scheduled for Saturday, August 27th at the club's dark sky site,
Hidden Hill Observatory
Anyone can come to our open houses, not just club members; but you cannot go
there without an escort. We will meet at the corner of Mines and Tesla Roads
at 6:30 PM, then caravan to the site on a drive that takes about 50 minutes.
The admission is $3/car; please bring the exact amount. There is no gas on
the way, so be sure to gas up before leaving. The site is essentially in the
wilderness, so there is no electricity and water, and there are only a couple
of pit toilets. Cell-phone reception is iffy at best. While there is a
picnic table there, you really should bring your own chair. If you need to
see what you are doing, bring a red LED flashlight, not a white-light
flashlight. And use masking tape over your car door and interior lights, or
pull the fuse. If you don't have a scope, you can always find someone who is
willing to let you look through theirs. And don't forget to bring your
binoculars. Expect to stay until about midnight and get back to Livermore at
around 1:00 AM.

The H2O Open Houses will be open to all club members and

members and their guests. Start and end times for the parties
will be announced later, but we usually plan to arrive at
the observing site about 30 minutes before sunset and wrap
up around midnight. Mark your calendars now!
Our Tesla Winery club star parties will have a new twist this year.
For those wishing to participate, each party will have a theme
and observing list associated with it. Themes suggested so
far include a mini-Messier marathon, lunar features observing,
planetary night, star cluster observing, beginner's night,
and constellation identification. If you have an idea for
another theme, please mention it to a board member during
The theme for July 30th's Tesla club star party will be the
planets. All eight planets will be visible, starting with Venus
and Mercury in the early evening near sunset and ending with
Uranus and Neptune towards midnight. Ambitious observers may
want to look for the asteroid Pallas too!
