 Today’s 88 constellations were formalized by the International Astronomical Union in the 1920’s. 
Our modern constellations started with the 48 listed in Ptolemy’s 2nd-Century Almagest.  
We will explore how new constellations were introduced starting in the 16th century
and take a look at some of the more than 100 that have been abandoned.  
This will be a preview for his two upcoming articles for Sky & Telescope.

 

Ray Harris has been a member of LVAAS since 1985 and has served as both Treasurer and Director.  
After graduating from Yale in 1972 he served five years in the Navy as a nuclear engineer on a submarine.  
He settled in the Lehigh Valley in 1980 when he accepted a job with PP&L.  
Ray started collecting antique star charts in 1987 and has accumulated an extensive collection or original material dating back to the early 1500’s.  
He has lectured widely on the history of celestial cartography
and his article “The First Deep-Sky Atlas” appeared in the January 2022 issue of Sky & Telescope.

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

WELCOME!

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.
