Object(s): NGC 7048
Category: Planetary nebula.
Class: 3b
Constellation: Cygnus
Data: mag 11.3(p) size 61", mag. of central star 19.1
Position: RA 21h:14m 15.2s DEC +46:17' 19"
Description:
This planetary is relatively easy to find in northwest Cygnus. This pn
showed no color, no central star, and was uniform in brightness except for a
small section on the northwest edge. The edges were diffuse. The pn is
located in a nice star field. 3 stars were seen in the nebula, one on the
northwest edge, one on the northeast edge, and one a little way in from the
northwest edge. The star at the northwest edge was very faint and only seen
in moments of good seeing. When used with the 35mm Rini and Paracorr
the orion ultrablock improved the view of the pn at 164x. But little
improvement was noted with the filter at 408x.
