stupid, but ...

I know, I know, never try to compare to Hubble, but it is hard to resist stacking against the benchmark. For the record, image of M57 core was initially processed by Johannes Schedler who extracted most of the detail from the data available. Running between the control room and telescope itself for tweaks and adjustments was shared between Philipp Keller and yours truly.

(this is cheating actually, I reduced Hubble image 3 times for comparison to be meaningful)

PS M57 / Ring is MUCH smaller than Helix. It is roughly 80 by 60 arc seconds, nearly 20 times smaller.
