Hello Cloudy Nights,
I recently finished processing my image of M42 in tricolor narrowband; however I'm having difficulty trying to get it to look "right." I do like the blue, orange, and purple color palette that I ended up with but in some areas (specifically in the orange) the color looks really blotchy. Also, in the low signal areas, the luminance seems to have blotchy regions (really apparent in the upper left of the image) and there's a lot of really bright pixels throughout the image. Finally, the nebula ended up looking rather blurry, especially on the outer edge, but the stars aren't elongated. My processing was limited to using HDRCombination to preserve the core details, deconvolution, MLT for denoising on the Ha (to be used as luminance, LHE on the luminance, combining in SHO, SCNR to remove green, a series of curves with masks to slowly shift the colors to my liking, ACDNR for another round of denoising, and then two rounds LHE to increase local contrast. Below is a Google Drive link to a folder containing all of the stacked images and the final XISF file and the image posted on Astrobin. I've also uploaded a smaller version to this post. I'd be more than happy to provide any additional information or files if necessary. The images were captures with an ZWO ASI 1600MM Pro through an Orion 8" f/3.9 astrograph on a guided Atlas EQ-G. Any comments, suggestions, and critiques would be greatly appreciated! Thanks!
