I took my old Eta Carinae data and used the new process as discussed in the Tarantula thread.
Since the (SII-OIII) mask showed a fair SII signal remaining I mapped the SII signal to magenta. Ha and OIII were mapped to red and cyan respectively.
High resolution here.

I'm fairly pleased with the result.
I will now try it out on more challenging objects.
Comments welcomed.
