      This is a recent image, shot on 4/13 and 5/11/2013 from a dark-sky site
      near Anza, CA. The imaging train is a 12.5" PlaneWave scope with a
      QSI-640ws camera operating at f/8 using an OAG. Integration times were
      170:70:60:50 minutes LRGB, 5.8 hours total. Median FWHM in luminance
      was 2.9 a-s before processing.

      The image can be seen here:

      <http://www.oc-aisig.org/zenphoto/albums/Astronomy-Images/siamese_lrgb_3\
      .jpg>

      Click on the image to see the full resolution rendition which shows more
      detail in the galaxy cores.

      Processing was done with CCDStack for the "heavy lifting", ExCalibrator
      for color balance, and PS for final adjustments. This target is a bit
      tricky to process because the galaxy cores are fairly low-contrast, and
      there aren't a lot of amateur images of this field for use as
      references.

      Thanks for looking - comments and criticism welcome...

              You are pushing 12.5" to the limit!
