Beautiful image of one of my favorite objects.  The nebulosity detail is extraordinary.

A good example of how aperture can change the way a target looks.  We think of this target as a cowled druid with a cape.  Its clear from this image that the dark recess normally seen where his face would be is in fact NOT a recess at all--you have picked up structure in there that gives the nebula a 3 dimensional look.  Pretty cool
