This allows for the capturing of some of the more faint areas of the nebula along with the brighter core. Having said that, I did have to dial down the brightness of the core in post processing to keep the dynamic range under wraps.
I will bow to your knowledge. You've got the image and skills to back it all up.
Thanks for sharing.
