Hi Astro'liano's
Last weeks Helix I was happy with, This one has two nights data combined, 4.75 hrs, 19 x 15mins. Also spent more time processing. It is most likely a bit red strong but seemed to be needed at my level of processing as the aim was to lift the "eyebrow" ? I have accomplished that I think ?
Added EDIT : Just looking at the pic and have notice I have left/worked an unfeathered selection just outside the Helix perimeter 
Edit 2 : Have checked JohnH's Helix out ! Wow John, I feel like i'm back on Dslr 
So I needed to bump my levels up, hence adding a third Image, where we'd be without guy's like yourself 
cheers.
Hope you find it worth a Squizz, the second is a pixel crop
CC never goes astray
Thanx for looking.
