I gave it a try Freddy. Everything seems surprisingly bright for only 60 second subs, which has me confused.
Indeed the object is small. I was just running into the same sort of thing with my M104. Only so much can be done with my data using a big crop - especially since that limits binning, and I'm probably better off with a wider-field crop. Same might be true here.
It doesn't take much of a stretch at all for things to start blowing out full white, including that ring of M57 plus most of your stars. Not just that one really bright star, but lots of them. Weird.
Unless this was an unusually high ISO, I'm befuddled. Might want to treat this as a multi exposure target, like M42 and the Triangulum? Or try to blend various stretches here in layers. The stars are easy enough for the background, there's good color and a core blur will rescue them from max saturation. I tried different HDR settings under Reveal Core - lowering the detail size way down will start taming down that fat white ring, even to where it is quite thin as is seen in some M57 internet images, but some of the surrounding detail gets weird at the same time.
So, I don't have any good version of this as yet..
