I like your shot. Much redder and more detailed than mine.
I just captured this last night. I have a much wider FOV, and less resolution on the PN itself.
What is interesting is just how LITTLE information there is about it. I was trying to figure out some details about it. There appear to be a few dark patches just below the nearby bright star, the kind of dust obscuring dark nebula that covers stars in certain areas. But I can find nothing in the usual sources. It hardly gets a sentence in Wikipedia and less most other places. And nothing about the area.
I was really thinking that my rig was not pointed correctly. I had to manipulate the screen stretch in Luminance and pretended to convince myself that I saw some change in the background where I thought the ring may be. Then, I started blue, and green, and definitely saw NOTHING that would indicate the ring. I went to sleep, and let SGP do the rest of the night (and another galaxy later on). So, I did not see the red subs. But, they did show something when I brought them up this evening. I guess I am saying that the ring is really very faint. I have not processed really yet, but it is a kinda cool object.
