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
The Large Synoptic Survey Telescope (LSST) is an 8.4 meter
telescope under construction in Chile. The talk will
describe some features of the telescope and significant
differences from other 8 meter telescopes. An interesting aspect of
the telescope is the problem of managing the vast amount of data it
will generate every night, far exceeding the sum of all other optical
telescopes. The scientific goals of LSST and its mode of operation
will give amateur astronomers immediate direct access to all of the
images, better, faster and deeper than SDSS. Lawrence Livermore
National Lab (LLNL) has made significant contributions to this project.
While working at LLNL, Dr. Dossa has been involved in the design
of the LSST data management system. A few of his previous projects at
the lab included project management for the acquisition of BlueGene/L,
at the time the fastest computer in the world and as software manager
for a large computer program for modeling stellar evolution. Prior to
coming to the lab he worked at Digital Equipment Corp in hardware and
software engineering. The Russian Academy of Science granted him
observing time on the Russian 6 meter telescope to search for an
optical pulsar. He has PhD in theoretical physics.
H2O Open House
Our next open house is scheduled for Saturday, August 16 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 a flashlight,
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.

Barcroft High-Altitude Star Party
This year's White Mountain
star party will be held from Sunday September 21st through Friday September
26th. This joint venture with the
Eastbay Astronomical Society
is held at the University of California's
White Mountain Research Center.
The fee for attending is $65 per person per night. The location of the site plus its altitude of 12,450 feet
assures exceptional viewing conditions. But it also offers some interesting challenges for people who
are not accustomed to the high altitude. Please visit EAS's
for a detailed description of this year's party. To sign up, contact
TVS has back issues of S&T and Astronomy magazines freely available. If you are interested in being a recipient of
these valuable resources of astronomical history, please make your interest known at a forthcoming club meeting. First come,
TVS Logo Wear
You may have seen some TVS members wearing shirts and jackets
embroidered with the TVS logo. If you are interested in obtaining an
embroidered logo item, you can do so by ordering whatever you would like
Land's End's Corporate Sales
section and specifying TVS logo #0118948. You will need to set up an account, which will
ask for the logo number and the TVS customer number (3452021).
TVS has also set up shop at
for members to buy non-embroidered TVS logo wear. You can have the TVS
logo put on t-shirts, mugs, buttons, hats, coasters, etc. You buy
through Cafepress, and Cafepress sends TVS a portion of the proceeds.
Visit the web site to see all the TVS logo possibilities.
