Corwin's Notes
=====
NGC 2982. JH had trouble with the position of this cluster. The NPD printed
in CGH is corrected on the errata page of CGH, and even that corrected NPD is
about 10 arcmin south of the scattered group that we've all taken to be his
object. That the correction is necessary is confirmed by checking the sweep
in the Herschel Archives: the north polar distance printed in CGH belongs to
the next object in the sweep, a star. Otherwise, the position looks to be
correctly reduced.
However, JH's description is of some help: "A cluster of about 20 stars 11 m,
and 2 of 10' [10.5] m, forming an oblong nearly in parallel; place of
preceding * 10' m." This fits the appearance of the modern identification
pretty well, though I do not see a "preceding * 10'".
For lack of anything better, we'll go with this object for now.

NGC 2982
14" (4/4/16 - Coonabarabran, 142x and 184x): bright, distinctive group of stars, roughly 10' x 6' E-W. About three dozen stars are resolved with many of the brighter mag 10.5-11.5 stars in a zig-zag pattern extending west to east. The brightest mag 10 star on the southeast end forms a wide 30" pair with an 11th mag companion. Another mag 12.5/13.5 pair at 15" is less than 2' NE. A 4' line of four mag 11-11.5 stars oriented NW-SE passes through the center and the remaining brighter stars are scattered within the outline.
