Thanks for the comments Jen, HOughy, Lester and Matt. Still a long way to go with this art/science of astrophotography.
Alex, not sure how you make a synthetic luminance layer but sounds interesting.
Greg, I did try doing a custom white balance with the 18% grey but the shots seemed very green. Maybe I shouldn't have left the LPS V3 filter on when I took the CWB.
Doug I did try some flats on this but couldn't get it quite as good. Maybe have to redo my flats. Will have to try darks as well instead of ICNR so I get some more imaging in - more lights and shorter exposure.
Thanks Spearo. I have done a version with changing the colour of the flame - just feels a little like cheating though. Have to try it without the filter and maybe a dark site.
