TVS Lick Observatory Tour: June 7th

TVS has arranged with Lick Observatory to have a behind the scenes tour on June 7. Unless required for official duty, our tour guide is expected to be Dr. Paul Lynam, Resident Astronomer of Lick Observatory, who spoke at TVS a few month's back. The tour is open to active TVS members only, and is limited to 30 people. The start time will be 6:30pm and the end time will depend on the weather and the interest of the group. Weather permitting, observing through the 36-inch Great Refractor is planned. Tours typically last 4.5 to 5 hours.

is now accepting payment for the tour, which is estimated at $20/person assuming that 30 people sign up for the event. Participation is on a first come, first serve basis. You can pay Rich directly; but if fewer than 30 people were signed up at the last meeting, then reservations can also be made via PayPal payment to TVS using our payments page. To pay for the Lick Tour simply fill in $20 under "Other" (or more, if paying for more than one person), write "Lick Observatory Tour" in the "Explanation" box, and then click on "Pay Now". The advantage of using our Paypal account is that refunds can easily be issued in the event that the tour is overbooked. If there is sufficient interest, it may be possible to arrange for a second tour at a later date.

Upcoming star parties

We have planned the following star parties: Please contact for further information.

The H2O Open Houses will be open to all club members and the public. The Tesla Winery Star Parties will be open to club 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 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 any meeting.
