American astronomer Ivan R. King, (1925?), graduated from Hamilton College in 1947 and received his doctorate from Harvard University in 1952. Starting in 1949, while at Harvard, and later in 1966, at the University of California, Berkeley, King created a catalog of 27 open star clusters, based on his study involving the dynamical modeling of star clusters (refered to as the "King models").
The amateur astronomer will find many of his 'King' objects listed on star atlases and observing guides.

While a few of the 'King' objects are already listed under other catalog designations such as 'NGC', the majority are unique objects, not listed in any other prior catalog. The majority of King clusters can be found in the Fall Milky-Way region of Cassiopeia and Cepheus.


On the left side of the webpage is my personal observation list of the
'King catalog of star clusters'.

I currently have all 27 possible King objects visible from my Pittsburgh, PA latitude of around +40.

Hope you enjoyed the visit. Come again soon!
