Markarian's Chain is a string of related galaxies in the Virgo Cluster, about 55 million light years distant. Messier 87 is the largest, and is upper-left-center. The arc of the "Chain" is clearly visible, as are many other distant elliptical galaxies. Zoom in to the full size image and many "stars" become fuzzy dots of galaxies as well.
This is a rough processing as I have one more run of data to add (some Luminance, some color), and as such I haven't cleaned up the satellite trails or bad columns yet.
Update 2013-05-25: I never did get around to cleaning this up. I have since learned how to kill those hot columns nicely, among other things. I will eventually re-post this under a new date.
