I was finally able to observe this planetary nebula from my SQM=19.1 backyard in La Serena, Chile, using my 12" dob. My notes read:

At 43x already visible as a fuzzy star. At 188x a central star surrounded by an oval glow. The star doesn't lie exactly in the middle bus is displaced east along the major axis of the oval. Some dark features are barely visible in the disk. At 319x the disk seems to be open at the west side. Closer inspection reveals a very thin edge with a dark gap between the edge and the central star. Occasionally a dark gap appears between the central star and a thin, east edge.
