I have a recollection of a paper I found years ago which had details of Helix's colours. It listed a Helium line which gave a yellow cast to sections of the eye beyond the blue-green central part. I haven't been able to find the reference again, unfortunately, but there are Hubble and ESO images which seem to support this.
Anyway, methinks this is a superb image

Very kind. You'll also be pleased to know I tweaked magenta level via the green curve in photoshop (same url)

Well done!
Ta...This was taken in average seeing, hence my hope is new data will show more of the faint fuzzies that lurk behind the central OIII pool.
