One of my favorite edge on spiral galaxies imaged from Bortle 8 urban skies. This image of NGC4565 was taken under bright skies looking into the brightest part of the light dome of Halifax. Masked stretching and processing the galaxy separate from the stars is still able to pull out a fair amount of detail from a short 57 minute  exposure. I'm going to have to acquire a couple of hours from a dark sky site to really pull out all the detail available in this object.

"NGC 4565 (also known as the Needle Galaxy or Caldwell 38) is an edge-on spiral galaxy about 30 to 50 million light-years away in the constellation Coma Berenices. It lies close to the North Galactic Pole and has a visual magnitude of approximately. It is known as the Needle Galaxy for its narrow profile. First recorded in 1785 by William Herschel, it is a prominent example of an edge-on spiral galaxy." Wikipedia.
