If the quality of lum matches the quality of synthetic lum then ok I’ll try it.
I have read that the unweighted average of individual RGB components does not give an optimal snr, different weights for each colour based on scaled noise estimates should be assigned.
Pix Image integration tool
Select RGB files
Parameters default
Combination-average
Normalisation = additive with scaling
Weights=noise evaluation
Scale estimator=iterative k sigma
Generate integrated image = enabled
Evaluate noise = enabled
Pixel rejection = no rejection
Clip low range =disabled
Clip high range = disabled
This came from Jim’s Pixinsight crib sheet.
Thanks again Rodney.
Any others ?

The settings that you list there George are the exact same ones that I use for creating a synthetic luminance.
I'm pleased that you are getting some clear skies up north as I cannot say the same for us here in NSW.
