 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.
