M13 Drizzled and Cropped
On my "quickie" version of this, Mike in Rancho commented that I'd blown out the core and he couldn't see the propeller. So, I re-edited it. This time, I drizzled the L, R, G and B channels, then cropped to a nice square 1200x1200 to really highlight the cluster. I took extra care to keep the core of the cluster tamed as I stretched and applied curves.
