NGC 2261 is near NGC 2264 and much easier to see than the Cone nebula.

The bluish nebula in NGC 2264 is the brightest part.
Daniel, John Herschel gave two different positions and hence we have two NGC numbers for the galaxy 1269 & 1291.
See the historical notes regarding NGC 1269 and 1291 in the following.

"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." Dr. Harold G. Corwin, Jr.
