I found this one more difficult to process due to the very bright core within the Orion Nebula.
For this, I captured two sets of exposures and combined them as an HDR image using the HDRComposition process in PixInsight. This is only ~30 minutes of data, as I have a limited window of targets toward the south, due to trees being in the way. Will try and find a better place to setup the telescope next time, and hopefully capture more data. Might also try the L-Pro filter next time, to see how the colors come out.
To fix the overly bright core in this image I first tried using HDRMultiscaleTransform, but this kept washing out and destroying the color towards the center of the nebula, regardless of the settings I used.
So I instead used varying sizes of masks to gradually lower the highlights of the core in phases, with each mask getting smaller and smaller until I ended up with this result.
