Wow! They're great Scott!
I think that's the first time I've seen the Omega in the Omega neb. I find it easy to pick the swan... and haven't yet picked the lobster
. Unless I'm just kidding myself, the omega is just below the swan... it's a darker shape in the nebula, a capital omega written at about 30 deg up to the right in this frame. I can see how it would stand out in a shallower exposure.
I see what you mean about the noise in the helix, but you've got some great deep detail there. It looks to me like there's some very faint detail on the verge of coming out, but I think a lot more 30 minute subs would be required to achieve a better S/N ratio... maybe some 30 minute subs on Houghy's cooled DSLR???
Great stuff anyway!
