Shockwave should be more blue though as its O111 not Ha. Overall seems a bit too much red. Some nice detail in the shockwave showing.

Thanks Greg, yes, there is a lot of OIII and its not showing much, no fiddling will fix it. The action creating Green is a bit odd actually, would have thought red from OIII and Ha would have been more logical, for Hubble pallete. Not overly happy with so much red myself.

It's a bipolar emission nebula. The star at the centre, HD 148937, is believed to be at least a triple star system. It includes a short-lived, highly luminous O7 type star of about 40 solar masses. The material in the nebula was ejected from the poles of this star in several bursts beginning about 4,000 years ago.

Thanks Rick. Interesting you going for that pallete too,mmmm. I tried to use synthetic SII for Red, with a bit of basic fiddling, it just didnt look right. Ha RGB seems popular with other samples Ive seen, maybe that works best.
