Markarian's Chain

This has been a favorite since I first saw it.  Looks like a string of Jewels tossed across the sky.

Not as much detail as I would like considering the 5.4 hours of RGB imaging (5 minute subs), however I had 50% moon for 3 hour of the imaging time so  this may be close to the best I may get under those conditions.

Nice. And nice colours too.

If you do a dynamic crop before DBE (see http://www.lightvortexastronomy.com/tutorials.html ), you'll get much a much better background sky and your gradient should all but disappear.
