Corwin's Notes
=====
NGC 1269 = NGC 1291. Though JH claims to have seen them on the same night (1
November 1836), I think that he has some mistake in his records. His data and
description for NGC 1269 are identical to those for NGC 1291 on that night
with two exceptions. First, the RAs differ by 2 minutes 34 seconds, and
second, he adds a diameter to his description of N1291 (90 arcsec), while
N1269 has none. Otherwise, the data are the same: NPDs 131d 43m 11s, and
descriptions "vB, R, gmbM (hazy)."
He has two observations of N1291 (on the second night, he called it a
"mottled, but not resolved" globular cluster). His RAs for the two nights
differ by 10 seconds, and he suggests that one is in error. Not knowing which
one, he simply took the mean value and used that for GC. The galaxy is so
large that both positions fall within the image.
The identity was first suggested by Robert Innes in a note in Monthly Notices
62, 468, 1902. He could not find N1269, but had no trouble seeing N1291.
Dreyer, in his IC2 Note, did not go so far as to repeat the supposition of
identity, but succinctly summarizes the other evidence.
I don't think there can be any question of the identity of the two numbers --
though without seeing JH's observing logs for that first November night of
1836, I of course cannot say this with utter certainty.
