This image was created by median combining 7 x 90 second unfiltered images taken with a Takahashi Epsilon 250 with SBIG ST-8XE CCD. The image has been cut down to be 20 x 20 arc minutes in size.
NGC 891 (or Caldwell 23) is a edge-on spiral galaxy with a distinct dust lane. It was discovered by William Herschel in October 1784. This galaxy is perhaps the best example of a near-by spiral galaxy viewed edgewise. Note the small companion galaxies above and beneath the disk.
