Description

Pretty decent seeing from my backyard allowed capturing this fascinating planetary at bin 1 (0.5 arc seconds per pixel). You can even see the wispy of the secondary ring just outside the bright inner region. There is an even fainter outer ring, which does not show up here. I combined two 360 second line-stacks to produce this image. The extra time reduced image noise a lot.

If you look carefully, you can also see a couple of stars on the disk at 5:30 and 7:30, relative to the central star, about half way to the edge. The one at 5:30 is more obvious. There are a couple more stars hidden on the disk, but they are lost in the mottled surface texture.
