Wow! At least 20 distant background galaxies, and most of that faint lumpy
fuzz is probably background galaxies as well, especially that nice little
tight cluster at about 10 o'clock and halfway to the edge of the frame from
831.
Great shot, as usual, Chris!

Hi all,
I had not shot this excellent edge on galaxy since my ancient ST8i days, so
here's a go with our latest camera, and now my best attempt yet at this
enigmatic object. Of special note here, is that this object has a B-V index
of nearly .9, and is one of the most dust reddened galaxies in the sky.
Unlike an object like NGC6946 in Cygnus where the Milkyways own dust yellows
galaxies and we have to process the image to help reduce this yellowing to
see what the object "really" looks like, this galaxy is yellow because of
its own equatorial dust lane material and not from our Milkyway. So I felt
that this color here should not be "corrected" since this is the galaxy's
true color and tells us so much about its dynamics and composition.
