Not seen this one on here so thought I'd ask. I understand extraction and stacking of Ha/Oiii data, and do it quite successfully. But I'm getting a dual NB Oiii/Sii filter soon, so I'm curious as to how that will work with an OSC?

Would it be correct in assuming that because the Sii is closest to the red channel, if imaging using that filter, one could just use the Ha/Oiii extraction algorithm for OSC then when combining the data using the Combine RGB tool in an SHO palette use it there as actual Sii?

I'm hoping that made sense

It is yes and you should be fine using the Ha/OIII combination. In combineRGB you can mix any data in the way you want, so if you specify the SII extraction is SII, it will be treated as such.

This is with the new Askar Oiii/Sii. I extracted Sii using Extract Ha.
