Has anyone tried MGC for narrowband yet?

I get stuck on choosing filters for RGB - it seems there is only data for Ha at the moment. Should we just choose R for SII and B for OIII for now?

not sure if that will work since typically more structures show up under narrowband and so using the broadband mars data could result in oversubtraction. but of course it is worth a try, just watch the official pixinsight video about tuning MGC.
