NGC2683
Spiral
Galaxy in Lynx

11/9/10
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. |
