Crab nebula re-processed

I had another shot at combining my full spectrum data and narrowband for M1. The narrowband was obtained using a OSC (Starlight Xpress SXVR H9-C) and the Altair Quadband. The original narrowband was stacked using Astropixel processor and the Ha and Oiii extracted. I then used the following tutorial for combining ha with full spectrum but I also added the Oiii to the green channel in the same manner.

Thanks Carole and Chris. :)

Now I really like the result.

But my question is this: what do these colours really represent now? I'm assuming the red is hydrogen and the green is oxygen. And as the filter combines Sii AND Ha into a red zone, and H-beta + Oiii into a green/blue zone is the magenta colour sulphur? Is hydrogen beta in there? :suspicious:
