 "My 50 Year Old A. Jaegers Telescope Returns Home"

Featuring James Chen


Last year during the height of the pandemic, I was able to be re-united with my old high school telescope that I had sold in college. After 50 years, my A. Jaegers 3-1/4 f/15 refractor has come home. This will be an informal talk about its recovery and remembering the good old days of the 1950’s and 1960’s of building telescopes, and lusting after classic equipment made by Unitron, Cave, and others. 

James Chen is retired from the Department of the Navy and Federal Aviation Administration where he worked as a Radar and Surveillance Systems Engineer. A guest lecturer at local Washington DC/Northern Virginia/Maryland astronomy clubs on amateur astronomy topics of eyepiece design and optical filters, he wrote a short Astronomy Magazine article on Dobsonian telescope design November 1989 and served as a sales consultant to two Washington DC area telescope stores for over 30 years.

James is a frequent speaker at Astronomy clubs near his home in Virginia and has also spoken at Princeton on the topic of Astronomy for Older Eyes.

James has authored five books for Springer Publishing’s The Patrick Moore Practical Astronomy Series including the titles:

THE LEHIGH VALLEY AMATEUR ASTRONOMICAL SOCIETY -- 620B East Rock Road -- Allentown, PA 18103 -- 610-797-3476 --


Founded in 1957, the Lehigh Valley Amateur Astronomical Society (LVAAS) is one of the oldest continuously-operating amateur astronomy organizations in the U.S. The mission of LVAAS is to promote the study of Astronomy and to maintain a meeting space, observatories, and a planetarium.

LVAAS operates two astronomy sites: The South Mountain site in Salisbury Township is the headquarters of the Society. It has a planetarium with a Spitz A3P projector, a 21 foot dome, meeting space, the Red Shift store, library, workshop space, and three observatories. The Pulpit Rock site near Hamburg is LVAAS's members-only dark sky site. At 1600 feet above sea level, the site features five observatories and a pad for member's scopes.

Members who receive training on the scopes may obtain keys to the observatories. LVAAS also maintains a rental "fleet" of telescopes that members may rent at low cost. Members also receive access to The Observer, our online newsletter, as well as reduced subscription prices to Sky and Telescope and Astronomy Magazine. If you want to learn more about astronomy and LVAAS, please join us at our next public star party.
