V = 8.4;  Size 6

18" (8/17/04): at 225x, ~30 stars are resolved in an 7'x3.5' group, elongated N-
S.  A couple of scattered groups of stars are to the south, but are apparently 
detached.  7 stars on the south side form the outline of a perfect rectangle 
with the eastern vertex the brightest star in the cluster (mag 9.5 SAO 34332).  
There are no stars within the interior of this rectangle.  The richest group of 
stars is just north of the rectangle.

17.5" (10/5/91): about 30 stars in a 7'x3' region elongated N-S.  Set over a 
background of some unresolved haze on the N side of cluster.  Includes six 
brighter stars with a mag 9 star on the SE side.  Fairly rich in faint stars on 
the N side although not rich in other sections.

Historical Research Notes / Correction for NGC 7261
NGC 7261.  JH's cluster is probably the scattered group of pretty bright 
stars, stretching nearly north-south across an area 15' by 10', about 20
seconds preceding his position for the bright star on its following edge.
There is a smaller core (7' by 5') of generally fainter stars about five 
arcminutes north-northeast of the center of the larger group.  Is this 
perhaps a background cluster? - Dr. Harold G. Corwin, Jr.
