Sharing the Wonders of the Universe
The purpose of the society is to foster interest in astronomy, to encourage and assist members in the study of astronomy and in the making and use of astronomical instruments.
The Sacramento Valley Astronomical Society (SVAS) is a nonprofit educational society. One of the oldest astronomical societies in the United States, it was founded in 1945 by 50 local astronomy enthusiasts. SVAS members range from young students and amateurs curious about the night sky to many college professors and even a world-famous comet hunter.
The SVAS serves the community of Northern California through its successful and long-standing Outreach programs and its membership through programs such as telescope workshops, loaner telescopes program and member star parties. The SVAS maintains an Observatory on Forest Service lands high in the Sierra Mountains for use by its members.

When the science class gets to the subject of Astronomy, we can help.
If you just like to learn all you can about Astronomy, we get that.
If you have your own equipment, we've got a place for you.

In addition to Public Events, we make our scopes available by appointment. . .
School star parties are events where SVAS volunteers go out to a host organization’s planned event with telescopes and educational astronomy presentations and activities. Please note that this is an educational, not entertainment, program. For those who qualify we will travel to an appropriate location of your choice within a 30 mile radius of Sacramento.

In June, July, and August, amateur astronomers often set up telescopes at Glacier Point on Saturdays, and astronomy walks or talks are also be offered in Yosemite Valley, Tuolumne Meadows, and Wawona.
Black Butte Lake is the perfect place for a star party. The skies are dark and comparable to Shingletown or Adin. Access is easy and the roads are excellent. Camping and RV sites are clean and spacious. Water, restrooms, hot showers, an on-site dump station, wildlife and cooperative rangers all will contribute to a comfortable and pleasant stay. All lights will be controlled by the park rangers in the campground, so light pollution will be at a minimum.
Few places in California combine such pastoral character with dark skies and comfortable camping. And in spring, the rolling oak foothills will be carpeted with green grass.
Because of limits on the number of people and vehicles, this star party is private. Attendance is by invitation only!

Lonnie Robinson brings you the very best in Amateur Telescope Making (“ATM”). He can help with all aspects of Dobsonian telescope building from design and construction to mirror making. He is happy to help with “telescope tune ups” involving mirror cleaning, collimation, and adding equipment upgrades.

Engineering Lightweight Dobsonian Telescopes
by Lonnie Robinson
Updated 2013
John Dobson really started something with his Dobsonian “Dob” telescope design. He enabled the average Amateur Telescope Maker “ATM” to create a large and very stable telescope with common workshop tools. In this article, Lonnie shares his personal thought process and his lightweight Dob building adventure with you, hopefully adding some additional fresh ideas to help inspire your new Dob telescope project.
Each month, on the Saturday closest to the New Moon, members and their guests gather under the stars for some great dark sky viewing.
