Dietz that is a very clear image.
This object is hard to see visually because the central star is fairly bright (mag 9.5). The PNe (mag 10.9, 136" diam) is best seen with a filter.

Fabulous image. Clearest I've seen of this object. I have attached a colourised version made with three different images using CDS's Aladin Version 4 - at least as a comparison.
I have attached some information on this planetary for you, giving some information on the visual nature of this planetary. This might be useful alongside your attachment image.
What can I say but a Gorgeous image!
Lovely detail and very smooth.
Keep at those PN! with you f/18 setup , it is really pulling in fantasic detail..
cheers Gary
