M27 in Ha and OIII

This is another try at narrowband work, using Ha in the red channel, OIII in the blue and OIII as a pseudo green, following the Steve Cannistra method.
It's not really suited to pictures with lots of stars as they also take on the pseudo colours and have to be treated differently. Lots of work and finally I think I like the original colours more, but it was worth the effort to try and I'll do it again with more suitable scenes, but it makes for a most unnatural picture, like the Barbara Cartland of Cygnus.
Of course, it could be that I'm not much good at the processing side of the job, but I'll hopefully get better at it, then try again.
