I will do a repro as I look to have over stretched the galaxy. Too much noise in the fainter regions. I tried blurring it a bit more it wasn't working for me.

Kappa - seems to bring out more detail in the brighter areas.
Mean - seems to smooth the high noise background out.
You can make a psuedo luminance layer just by converting to gray scale.
