Size 8x7

17.5" (10/17/98): fairly high surface brightness nebulosity ~3'x2', surrounding 
three mag 9.5-10.5 stars at 220x.  At 280x, the brightest region surrounds the 
southern star (also the brightest star) and the star to the NE.  Just preceding 
this second star is a small knot which does not appear to be surrounding a star.  
A 3rd involved star on the preceding side has the weakest halo.  There is an 
additional pair of stars nearby to the SW but they do not appear to be 
surrounded by halos.  The entire group is encased in a diffuse glow and the 
surrounding region appears to be dusty.  IC 5132/5133 are very weak nebulae 
surround mag 12 stars ~5' NNW.

17.5" (9/23/89): fairly bright reflection nebula surrounded three bright stars.  
The brightest portion includes the southern star.  Also a bright knot is at the 
N end which is not surrounding a star (or the star is embedded).

13" (7/20/85): fairly bright with 0III filter but dims using a Daystar 300 
filter.  This nebulous region includes four or five stars and appears brighter 
around these stars.  A small knot is at the north end and a second knot is at 
the south end.

NGC 7129 is a diffuse nebula enveloping three pretty bright stars.  Both 
Herschels described it the same, and JH measured the position angles and 
distances of the two flanking stars with respect to the brightest, more 
central southern one, BD +65 1638.  His mean position for the nebula, adopted
in GC and NGC, is for that star.

Bigourdan apparently did not read JH's 1833 description before he examined the
area in the 1884, 1889, and 1895.  Bigourdan applied NGC 7129 only to the
patch of nebulosity to the northwest of JH's star C, the northeastern of the
three stars.  He also found a "new" nebula in 1895 around JH's star A, the 
south-central of the three.  This now carries the number IC 5134 (which see).
Another "nova" from Bigourdan, NGC 7133 (which see, below), was apparently
an illusion as there is nothing near his place but faint stars.

NGC 7133 does not exist.  Bigourdan describes it as a "Pretty extended area,
perhaps 2 arcmin across, in which I suspect some extremely faint nebulosity,
at the extreme limit of visibility."  There is nothing near his single 
micrometrically measured position but a few faint stars.  My guess is that
this is another of what he would call his "fausse images."

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.
