How much does oxygen imaging contribute in galaxies?

It was interesting to view the nebulae in the spiral arms in different palettes. I planned LRGB + SHO in the beloved Hubble palette and, in addition to oxygen, I also collected 7 hours of sulfur. From the three processing options (SHO; HOO), I chose LRGB+Ha+OIII.
