just off the S end (46" from the center) and a mag 13 star off the N end (1.0' 
from center).  Extremely faint stars are superimposed at the W and NNE edge.  
Slightly brighter along the W and E side of disc and has a slightly darker 
center (weakly annular).  No central star visible.  Located 3.3' ENE of mag 8

Historical Research Notes / Correction for NGC 7048
NGC 7048.  There are several stars and faint knots "in" the interior of this
planetary.  Most of the stars are only optical companions along our line of
sight to the nebula.  One, however -- clearly seen on the DSS2B image and no
other -- is the central star.  I've adopted the position of this star.  Just 
east of this on the DSS2R image is a tight group of faint knots; the star has 
disappeared from this R-band image. - Dr. Harold G. Corwin, Jr.
