Contemporary Visual Observation(s) for NGC 1269 | |||
NGC 1269 = N1291 = E301-002 = MCG -07-07-008 = PGC 12209 03 17 18.2 -41 06 26 See observing notes for N1291. Discovered by JH (h2518) on the same night as N1291! Strangely, the objects are given identical declinations and almost identical descriptions! Could he have reobserved the same object unknowingly? In Mon. Not, Vol 62, p469, Innes comments "not visible in the 7-inch. This is perhaps the same as NGC 1291, observed by h on the same night. H gives for the latter exactly the same declination and description as for h2518." Listed as nonexistent by Carlson and repeated in RNGC. | |||
Historical Research Notes / Correction for NGC 1269 | |||
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 succintly 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. - Dr. Harold G. Corwin, Jr. | |||
Correction Disclaimer | |||
As with all corrections to the NGC and IC Catalogues, there is a certain margin for error, even though the evidence supporting the correction may be strong and compelling. It is with this in mind that we ask the user to use this information as 'Most Probable', but never to assume the correction is 'Absolute'. All published corrections are based on an exhaustive 'paper chase' of the historical record back to the original discoverer's published notes/papers, and are therefore based upon the historical accuracy (or inaccuracy) of those particular notes/papers. In short, Caveat Emptor! - Robert E. Erdmann, Jr. | |||
