DescriptionThe Deer Lick Group is a classic collection of galaxies. The field of view evokes a powerful illusion of depth, looking out over the disk of the great spiral NGC 7331 (some 50 million light-years away), to the smaller much more distant galaxies beyond. I was initially stumped by the image processing challenges of this complex field of view, which I shot way back in summer of 2011. I put the raw frames aside until this past month, when I finally tried again to "lick" the personal processing challenges of the Deer Lick Group .
