Next General Meeting
Note that our speaker this month will be in-person, so please join us at Chabot if you have tickets (which are now sold out), or on Zoom if you do not.
Our guest speaker for the evening is Dr. Leonard Tramiel, Chabot Board Member, EAS Member, and Professional Skeptic
TITLE: Fake Color to Fake images
There is currently a flood of fake images on Social Media, even in astronomy. How can one tell which are real and which are fake? In this timely lecture about the image capabilities of AI, Dr. Tramiel will give us some important tips on how to tell which are which.
Telescope Makers’ Workshop
The Telescope Maker’s Workshop is one of few regularly scheduled such workshops in the world! Every Friday from 7 to 10 PM, amateur telescope makers from the bay area meet at the Chabot Space & Science Center and learn how to grind, shape, polish, and figure mirrors for reflecting telescopes, under the guidance of EAS volunteers. The workshop is free; participants pay only for the mirror blanks and grinding tools, which generally cost between $100-$300, depending on the size of the mirror. All the instruction, grinding grit, testing equipment, and camaraderie is free of charge! For more information, email Richard Ozer at pres@eastbayastro.org, or come by the workshop any Friday to see what it’s all about.
Dr. Simon Steel is Deputy Director of the Carl Sagan Center at the SETI Institute, located in Mountain View, California. He is interested in galaxies, black holes and, of course, aliens.
Outreach
EAS sends volunteers to schools, libraries, and anywhere curious aspiring astronomers gather. EAS volunteers bring their own equipment or borrow telescopes. Students, parents, and teachers are always thrilled to look through the telescopes and ask questions. You’ll meet all sorts of interesting people and provide a unique and inspiring experience to kids and parents who may have never looked through a telescope before.
Inquire about and request visits by e-mailing EAS Outreach Coordinator Raymond Howard at outreach@eastbayastro.org. Visit our outreach page to find out about upcoming events.
Members Only Viewing Nights (MOVN)
Once a quarter, we schedule a Members Only Viewing Night at the Chabot Telescope Deck for both EAS and Chabot members. This is our opportunity to look through Chabot’s historic instruments and research telescope, as well as bring our own equipment to share in a more quiet venue. The schedule for MOVN will appear in the event calendar below.
Calstar
Spring Calstar 2026 is scheduled for April 15 – April 19 at Lake San Antonio. Fall Calstar will be held on September 9 – September 13. For more information visit https://calstar.observers.org/
