Geez NII is difficult to blend into a SHO image. Fantastic data btw
Okay, first off! if you're going to replace NII with something I would definitely suggest SII in the case of M8.
The first image is a comparison between a SHO and NHO.
The second and third images are comparisons of SHO and NHO.
The third is a SNN. This is probably the most compelling of evidence. All of that grey area is where both the SII and NII signal is near identical. The red where the SII is stronger and teal where the NII is stronger. And there is a lot of grey!
What I found when trying to combine the NII (before doing these comparisons) was that the moment I tried to add in the NII it just sucked the colour out of the image and gave everything a strong purple cast as I assigned NII to purple.
Here is a link to a NSHON image where you can see where the NII and SII differ at higher resolution. There is some benefit from a interesting science stand point but in this case the NII and SII are so similar that it becomes a bit over powering.
