Hi to all
I eventually got enough data to justify posting a colour version of the helix. I was looking at getting some OIII but looking at the vast amount that would be necessary I'm going off that idea. This version has synthetic luminance. I might get some real luminance tonight to see if it makes any difference.
Cheers
Steve
