Corwin's Notes
=====
NGC 6421 is a brighter patch in the Milky Way that matches JH's description
and sketch pretty well. His position is pretty good, too. Note, however,
that the NGC description (taken from GC) is wrong. The correct description,
from the CGH Observations, should read something like "Cl, vL, r, connected
to Milky Way." I suspect that the NGC description was copied by mistake from
the CGH entry for h3702 = N6416, because the prime symbol is missing from the
3702 in the JH column in the NGC. Neither this object nor N6415 were numbered
in the CGH Observations, and JH does not have a note for either in GC
indicating why he entered them there even though he chose to not number them
for CGH. Dreyer copied the entries unchanged into NGC, also without notes.
Steve's Notes
=====
NGC 6421
24" (7/7/13): large, bright Milky Way cloud at 125x (50' field). Sharply defined by dust clouds on the west edge and along the east side up to the north end. Includes a nice string of a half-dozen stars (mag 9.5-11.5) on the southeast side and a couple of 1' pairs (oriented N-S) of mag 10.5-11.5 stars are at the east end of the cloud.
