Cheers everyone. I was planning to have a look at the cone last night but after an hour odd it was obvious the moon was just too close to it. All the subs showed a hot spot in the middle of them and it just looked like a white blob
I haven't been following that tonemapping method as written. I remove the stars and give the 3 channels a severe stretch, no blur, but you have to be careful not to burn em out. Here's the tonemap from this image. I then used apply image in PS to add the O3 and S2 to the Ha, gave it a sharpen, and use that as a Lum for the tonemap. I normally use a mask to sharpen after combining everything but got sick of sitting at at keyboard on this one. The hubble colours come up on their own and no magenta stars to deal with
Some images seem to show more detail this way, others, including this one, don't look much different from the traditional method. I tonemapped this one as I lost control of the colours in the other one
....as it changes the data rather than enhances it.
