It still turned out as if it were an Ha+OIII filter (all red). You need to split the channels and assemble it properly in one of the palettes so that you clearly get 2 colors. Even with a single duoband you can make two colors. The stars got a lot more attention)

There are two colors here: red - hydrogen and orange-yellow - S II, sulfur adds accents in the filaments. OIII is present only in IC 410, but it's not certain that it's worth emphasizing it more, it doesn't blend very well with the rest of the image's palette.
For an SHO palette, there's still not enough data, it comes out noisy.
