Typically, more detailed structures have a stronger emission where the detail is so they tend to show through with the Max function.

Thank you Colin for your advice. I was not aware of the Max function - so I also tried Min function
Unfortunately, the resulting image of linear fit (tried both ways) and Max(Ha, OIII) had even less noticeable detail near the core.

Cheers,

I was afraid that this is the case. The thing is that OIII has 2.5 times signal strength near the core and it is smooth/featureless, while Ha is stronger further away from the star remnant. I may need to try adding a bit more integration to Ha and just use master Ha as Luminance.

I like your idea Lee of weighting towards areas with most localised contrast. We could call this tool
WTAWMLCImageIntegration
BTW - I attached a stretch of both OIII and Ha - almost ready to start putting together the final image :-)
