A fine pair of spiral galaxies reside roughly 100 arcminutes from Stephan's Quintet to the north-northeast. These are NGC 7342 and NGC 7345. They are listed in the DSFG at magnitude 13.9 and 14.3, respectively. NGC 7345 has a reasonable 12.5 magnitude surface brightness. However, NGC 7342 rings up with a 14.4 magnitude surface brightness. Considering the relative ease with which these galaxies were detected, I am a bit skeptical of the RC3 numbers. A "Y" asterism of stars pointed the way to NGC 7342, only one quarter degree to the West. The galaxy was visible as a 40" diameter oval. No brightening around the core was detected but a 14th magnitude GSC star was seen immediately to the West. NGC 7345 appeared as a 30" x 10" elongation adjacent to the "Y" asterism. A check of a POSS image through DSS online indicated that I was seeing the bright core region but missing the outer portions of this edge-on spiral.
