DSLR-LLRGB post-processing workflow  according to Scott Rosen's video tutorial:
 
Original RGB image in Nebulosity 2.5:
  -DDP using standard settings

Original CB/DDP RGB image in Photoshop CS3:
 -Levels [Black-, Grey-, and White points]
 -Gradient eXterminator (1st pass Medium - Low, followed by 2nd pass High - Medium)
 -Convert to greyscale [This creates the Synthetic Luminance]
 -Convert back to RGB [RGB reconvertion is only done for easy of interpretation of PS histgram and tools]
 
Synthetic Luminance in Photoshop CS3:
 -Carboni's v1.6 Deep Space Noise Reduction [Removes noise from background, not DSO]
 -Curves, selective on weak dustlanes, with anchored background and highlights,
 
RGB processing in Photoshop CS3:
 -Curves and Levels to bring RGB to a comparable level as the Luminance
 -HLVG, medium strength
 -Carboni's v1.6 Space Noise Reduction
 -Carboni's v1.6 Less Crunchy, More Fuzzy
 -Increase saturation using Adam Block's method [3 copies of RGB, 3rd copy Luminosty blend mode, 2nd copy soft light blend mode, flatten all 3 copies] Repeat to taste, 3x for this image. This results in a slightly over saturated image
 -Carboni's v1.6 Less Crunchy, More Fuzzy
 -Gaussian Blur (2px)
 -Increase saturation using Adam Block's method [3 copies of RGB, 3rd copy Luminosty blend mode, 2nd copy soft light blend mode, flatten all 3 copies] Repeat to taste, 2x for this image.
 -Selective Color (Neutrals)
 -Luminance addition, blend mode Luminosity, at 100% opacity, flatten
 -Final tweaks using levels
