Hi Pete, thanks for the nice feedback!
In regards to the Blue LUM layer - I use PS and follow
Marco's method for including NB with RGB.
I had Dr. Malins version on my screen as a reference to see how closely I could match my results to his.
For this RGB image, there was no L filter used, just RG&B. (Pic 1)
Once I had the preprocessed masters combined, I layered a seperate Blue master on top of the combined RGB and used blend mode LUM.
Then I used a Hue saturation adjustment layer with a clipping mask (to only affect the LUM layer) and colorised it Blue (value 200, 97 saturation -46 lightness).
(Pic 2) This made the blue "pop" and with a touch of selective colour it looked even more natural.
I then created a b&w LUM layer and tweaked the contrast etc with silver fx pro to bring out more detail in the nebula. (Pic 3)
I've taken a snapshot of the layer stack as well (pic 4)
Hope that's useful

My favourite is the RGB. An inspiration to other photographers living in light polluted cities! I also would be interested to know about the blue lum layer.
Thanks.
