I was experimenting with the ZWO DuoBand filter that came with my ASI533mc using M42 as the subject. This photo is a combination of images: DuoBand (180sec) + RGB (120sec) + RGB (30sec) Stars. I processed the DuoBand subs separate from the RGB, producing two master images; one DuoBand the other RGB. I extracted the R, G, and B from the DuoBand before applying the NBRGBCombination process in PixInsight. I then used Bill Blanshan's technique for adding in the RGB stars (using the 30sec master).
The core is a bit blown out, but the overall result is not all that bad. I'll need to try some other objects using this imaging combination and processing technique.
