to what channels did you assign your Ha and SII data to??

I used LRGB mapped as - Ha:Ha:S2:S2

So the lighter reds are the S2 and darker reds are Ha

Thanks Rick, yep O3 is very faint, S2 wasn't too bad but a lot fainter than Ha.
I'm hoping to add more data next week and finish a tri-colour. I might need to dedicate a night each for S2 and O3.

I might need to get a narrower band S2 and O3. my LP seems to affect both, even Ha.
I compared the Ha from my backyard to one I took from a dark site and the difference is pretty significant.
