Sacramento Valley Astronomical Society

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.

  • Daytime solar viewing. Our volunteers, with safely filtered telescopes, will show your students the sun. We have white light and Hydrogen Alpha filters that reveal solar prominences.
  • Evening star parties. At your location, we can show your class(es) solar system objects and, if conditions are right, deep sky objects.
  • Loaner scopes.
  • Contact our Outreach Director -
  • Outreach/School Star Parties

If you just like to learn all you can about Astronomy, we get that.

  • Monthly General Meetings are a great place to come and learn more about Astronomy. We have presentations by our own club members and guest speakers, and the room is filled with like minded enthusiasts to share information.
  • Newsletters. The SVAS Observer is rich with information on upcoming club activities, special events, and articles related to astronomy in general. The SVAS Observer newsletter is published every other month.
  • Public Events. Check our events calendar for times and locations of our public outreach events, like Sunday Funday at Rusch Park, or any celestial event like comets and eclipses.

If you have your own equipment, we've got a place for you.

  • Monthly Star Parties. We meet at our dark sky site in the Sierra's on the Saturday nearest the New Moon.
  • Share knowledge. We've got members of all levels and some are quite proficient in the hobby. There is usually help nearby at Star Parties or in our email forum.
  • Outreach. A large part of our mission, and because it's fun, is our public outreach. Sharing the joys of Astronomy with the public is as rewarding as it sounds.

For the serious observer and imager, check it out.

  • Observatory Membership. With this you will have access that includes use of the 16″ Ritchey-Chretien, warm-up room, observing chamber and any other equipment available.
  • Imaging Gallery. Post your work on our website.

Amateur Telescope Making (ATM)

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.

Outreach/School Star Parties

In addition to Pubic Events, we make our scopes available by appointment. . .

School Star Parties

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.

For more information or to book an event, review the Star Party Guidelines

Citrus Heights Community Campout

Highlights: Swimming, BBQ Hotdog Dinner, Campfire Entertainment, Breakfast

For the attendees of the campout, we provide telescopic views of the evening's celestial objects.

Public Events

Our public outreach keeps us busy with these annual and special events. . .

    International Sunday 2018, Ch31 Good Day Sacramento with Walt

    Barnes & Noble

    When the Moon and Planets are in a favorable configuration, we set up scopes at the Barnes & Noble in Roseville. Solar scopes too.

    Sunday Funday

    Join us for the annual Sunday Funday a free family event! Your family will have a great time with inflatables and rides, pony rides, business and craft booths, music with live DJ, police K-9 demos, tot and kid fun zones, Food Trucks and more!

    SVAS will have telescopes for safe solar viewing.

    Celestial Events

    Events like comets, solar and lunar eclipses, meteor showers and planetary oppositions, are great opportunities to get the public exposed to the thrills of astronomy. Check our Upcoming Events to see if something is on the horizon.

    Observing Trips

      Yosemite Glacier Point

      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 Star Party

      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!
