As I was far from happy with my efforts processing first time around I went back and reworked my data last night. What I thought was noise turned out to be faint nebulosity which encircles the Helix. However I'm now thinking that 2 minute exposures were not long enough to do this object justice.
In order to try and overcome this I did a 2x2 binning midway through my processing. I didn't push the wavelets as hard and didn't zoom in as much.
I'm happier with the newer image but think I need to get out and get some longer exposures....
