Title: Complete reintegration and reprocess

Description: This data from 2021 was something that I knew I could eventually pull more from. I am really happy that I revisited it and applied the latest and greatest. This re-do actually incorporates 27 hours 46 minutes of subs since I am now relying on weighting and rejection, rather than culling sub-optimal light frames.

The dark dust in this object, (and other dark nebulae), is exceptionally prone to being washed out by the Xterminators, so I built a mask in the GAME Script which I used liberally to preserve the dynamic rage in the dark dust while utilizing BlurX, NoiseX and even StarX. The fact that StarX smoothed the dark dust was surprising to me, but it does. I think that @Russell Croman is aware of this, and suspect that newer versions will address this phenomenon. Maybe the AI is afraid of the dark? ;-P Regardless, this small issue is inconsequential to the overall value of these tools and easily addressed with the available tools in PI.

I used curves luminance and a mask to tame 56 Ori a bit, but I did want to leave it bright because I think that it's a good representation of its contrast with the dark nebulae near it. Generally, the comparably small number of stars in this area allows for the stars to be featured and not overwhelm the nebula.

It was @Kevin Morefield, who posted a recent outstanding image of this object shot with his new giant telescope set up in Chile, pushed me that little bit extra to re do this, so thanks for the motivation, Kevin!

Description: As I compared my result to other, better, images of this object, I realized that the bright star at the core of the brightest nebula and the proximate nebula at the "head" of the Boogeyman was blueish in my image, which is wrong. That star is yellowish, and so is the nebula it is illuminating.

I went back through my steps and found that, probably, applying Unsharp Mask caused this color shift since the color values lean red/green before this step, and blue/green afterwords in this brightest area.

I used Curves Transformation and a bit of HT to pull the colors in line with a GAME Script generated mask, using other stars and other well done images as references. I could have gone back to before the Unsharp Mask and protected the core with a mask and then retraced my steps from there, but at this point I need practice with Curves Transformation in PI, so I fixed the image this way.

There's a lot to learn about the pitfalls of using certain tools for sure.
