Special Dinner Lecture:

Observing the Sky: (Some) Astronomical Innovation From Then to Now
Stephen J. Edberg
Retired Utility Astronomer
NASA Jet Propulsion Laboratory, Caltech
Former Grand “Poo-baw”
Riverside Telescope Makers Conference

For more than 2000 years, innovative people have applied their ideas and insights into observing the universe. Unknown thousands of years ago, visual observers named sets of stars from the patterns they saw, sometimes using myths or animals, real or imagined, in their environments for the names. This became a convenience for astrologers and others talking about the sky. Planets were discovered and calendars were invented, and precession was discovered. Even computers and observatories were invented. More than a millennium ago, the first instruments for measuring star positions were invented. Used for surveying and navigation, improvements on these instruments and the developments of new ones led to new discoveries, especially when combined with new mathematical methods for calculation.

The invention of the telescope changed everything. Mountains and craters were visible on the Moon. Those moving points in the sky turned out not to be… worlds(?)! With moons! Telescopes and their mounts were improved, new inventions were adapted, and new methods of observation were applied to old and new problems by astronomers. The spectroscope, chemical photography, and the use of electricity and electronics literally opened up the universe to astronomers.

Steve Edberg, retired NASA JPL “utility astronomer”, started off working in solar physics at San Fernando Observatory (solar). He moved to JPL after about 20 months. He spent most of his almost-38-year career at JPL working on a variety of projects, Galileo, Cassini, Comet Rendezvous & Asteroid Flyby, SIM, and others including the International Halley Watch, at various levels of development, from proposal to flight operations.

Steve has received numerous NASA awards and has the honor of named real estate in the Solar System: Minor planet 1985QQ is now listed as (3672) Stevedberg. He builds telescopes and instruments in his garage and is also an avid bicycle rider and occasional singer.

Additional Remarks:


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. Find our next event on the calendar above.

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 month, 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 appears in the event calendar below.

Barcroft High Altitude Star Party

Reservations for the Eastbay Astronomical Society’s Barcroft High-Altitude Star Party are now open to members of both the EAS and Tri-Valley Stargazers clubs. This year’s event will be held from Sunday August 16 through Friday August 21 (with departure by noon of Saturday August 22). That’s six nights.

Before sending payments for reservations ($60 per night, per person), even if you’ve been there before, please contact Don Saito FIRST (donsaito@yahoo.com) to ensure the dates you wish to attend are available. You will also be asked to read the Barcroft Writeup, as it provides the information you’ll need to have a safe, comfortable stay, and what is expected of guests to this University of California research facility.

Space at Barcroft is limited to a maximum of 12 people per day, so to ensure you get the days you want, make your reservations early.

Barcroft is one the premier amateur astronomy view sites in the world, and it’s less than a day’s drive from the Bay Area to its location in the White Mountains.
