One way is to oversaturate the colour before hand and let the Ha as luminance bring it back to where you want it.

Cheers Greg! Yes a couple more to come if the weather holds (unlikely by the looks). Not sure I would saying using Ha as a luminance is risky but it does need to be treated with respect. At most, I only layer 25% opacity. I could tone down the brighter knots of emission nebulosity (perhaps with a multiply or softlight blend) and attempt to present the remaining areas at their retrospective brightness. The real risk is then whether the neb would display any depth and start looking mono tonal. Dark shades are always easier to colour, no doubt. Thanks for the good feedback. Perhaps you could get your RH pointing toward this target and other obscurities instead of hitting the same 'ol targets.

Thanks M&T! Yes, quite different. Its a shame not many imagers focus on the RCW catalog. It needs more attention. Its northern counterpart being the Sharpless catalog is by far more imaged.

Thanks Rick! Always happy to bring something new to the table. I hope others give the area a go.
