This splendid nearly edge on spiral galaxy in Lynx shows beautiful delicate dust lane details over its core. Shining at 10.6 magnitude, it spans 11 arc minutes wide. As expected, the B-V index (reddening) is +.89 due mostly to the yellowing effects of the dust. There are over two dozen minor faint galaxies in this image as well. Perhaps the brightest is just above and to the left of the core. This 16th magnitude inclined spiral is only .7 minutes wide and very yellow from extinction.
