I was just looking over some recent postings to "netastrocatalog", and I
noticed your posting of December 29 regarding an observation of King 12
(partially excerpted above).
I just wanted to clarify that the first 21 King clusters were NOT
discovered using the POSS, but were instead discovered by King AND
OTHERS, using plates from the (Harvard) 16-inch Metcalf refractor.
These clusters were reported in a paper "Some New Galactic Clusters", by
Ivan King, which appeared in Harvard College Observatory Bulletin 919
(pp. 41-42), of February, 1949 (note that this is before the POSS had
even been done). King notes that objects 2, 3, and 5 were discovered by
Rebecca B. Jones, and object 6 was found by Carl K. Seyfert (of Seyfert
King 22 _was_ identified on the POSS, and was reported in a paper by
King entitled "A New Galactic Cluster,", that appeared in PASP, v. 73,
pp. 163-164, April, 1961. However, this cluster had been discovered the
previous year by Setteducati and Weaver as Berkeley 18, so the latter
name is the preferred one.
King 23 to 27 were reported by King in a paper "Five New Open Clusters,"
PASP, v. 78, pp. 81-82, February, 1966. However, King 23 had already
been discovered as Czernik 28, King 24 as Czernik 32, and King 27 as
Czernik 40, so the Czernik names are prefered for those three objects.
