Next General Meeting

Saturday, June 18th, 2022
Our meeting begins promptly at 7:00 P.M.

Meetings are held in Virtual Space

Our guest speaker for the evening is Dwight Lanpher, Dark Sky Maine

The Leviathan of Parsontown

Any review of the history of astronomy will likely discover a large telescope called the “Leviathan of Parsonstown”. Built in Ireland in 1845 by the 3rd Earl of Rosse, it was the largest telescope in the world for 70 years until surpassed by the 100″ Hooker Telescope on Mt. Wilson. Each of two 72″ speculum mirrors were alternately mounted in a 54′ long tube, suspended between two purpose built castle walls. Amateur astronomer Dwight Lanpher will speak about his visit to Birr Castle, County Offaly, Ireland to examine “the Great Telescope.” His technical presentation will show detailed photos and drawings of how the telescope was operated and the modifications that were made during a $1,200,000 renovation in 1995. Images will also include the last remaining of the two, 3-ton, speculum mirrors examined during the return trip at its current location at the Museum of Science in London.

When not visiting ancient telescopes, Mr. Lanpher travels throughout New England and eastern Canada attending astronomy meetings as liaison for clubs in Maine, New Hampshire and a few in Massachusetts and observing at their star parties when the opportunity avails. Professionally, Mr. Lanpher works as a licensed professional Electrical Engineer.

Telescope Makers’ Workship

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.


Outreach

In person events are more limited because of COVID, but are being scheduled for schools and other community institutions. Contact us also for possible virtual events, or visit http://www.chabotspace.org for scheduled public virtual telescope viewing events]

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)

[In person events are more limited than in the past because of COVID, visit http://www.chabotspace.org for virtual telescope viewing events]

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.
