Had a few nights to try out some RGB imaging from by backyard. I don't do much RGB work because of my suburban location. To do the target real justice I would need far more time under these skies, but still some interesting bits resolved pretty well.
Using the annotate feature in Pixinsight there are 350 cataloged PGC objects in the field, with a handful of NGC objects as well. There look to be hundreds, possibly thousands, more that are visible in the deep background. Most of the deep background objects are more than smudges, but you can tell that they are not stars. I'm including the annotated version in one of the revisions.
