Tri-Valley Stargazers
Welcome to the Tri-Valley Stargazers Astronomy Club's web site. There is lots 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.
Most of these web pages describe some facet of our club activities and thus do not change very much. If you need more current information about something dynamic, try viewing the latest issues of our online newsletter.

The Latest News & Upcoming Events

January's Meeting
This month our speaker is Bruce Macintosh, who is an astronomer in the optics group at the Lawrence Livermore National Laboratory. He has worked on applying LLNL's expertise in adaptive optics to scientific problems, particularly astronomy, and was a founding member and associate director of the NSF Center for Adaptive Optics. His primary research interest is the direct detection and characterization of extrasolar planets. In his talk, he will describe the techniques used to image four massive planets orbiting the young star HR8799. He will also tell us the properties of these planets and what this tells us about planet formation. These images were obtained using the Keck II telescope. He will describe some follow-on projects such as the Gemini Planet Imager and a specialized space telescope that could see planets like the Earth orbiting nearby stars.

Dues are due!
TVS' membership year runs from January to December, so now is the time to renew your membership. Our membership rates remain unchanged from last year, as do the subscription rates for Astronomy and Sky & Telescope. We no longer offer the "Regular" membership level since we do not send out printed copies of the newsletter. Rather, at the "Basic" membership level we contact you via e-mail to let you know that a .pdf of the newsletter is available. The renewal form can be found on the back of the newsletter or on our website under the membership link. Please make our Treasurer’s New Year especially wonderful by sending in your renewal today.

TVS Volunteers Still Needed
We need a volunteer to be the Program Chairman! We also need a volunteer for the position of Vice President, and we could use more members at large to serve on the Board of Directors. If you wish to help with any of these positions, please contact any officer or board member.

Royal Astronomical Society of Canada (RASC) Handbooks and Calendars Available for Purchase
The club now has RASC Handbooks and Calendars available for purchase. According to the website the 2012 edition of the handbook is bundled with the Earth Centered Universe Planetarium Software. This free software will function through March 31, 2013 and will not perform predictions for events later than December 31, 2013. Prices are $25 for the Handbook and $17 for the Calendar. This increase from last year is due to both the RASC raising their prices and significantly raising their freight charges. See David Feindel for purchases, or contact him via email to arrange to pick up Handbooks and/or Calendars if you can’t attend the meeting. Visit the RASC web site For more information on the handbook and calendar.

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 through 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 Cafepress 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.
