Thanks for the detailed tutorials. Pixinsight has methods for color mapping, but I find your layer and slider technique in Photoshop easier to follow. I get tripped up a bit on the blending modes, and which buttons to click, for the different layer and adjustment layers, so they bear rewatching :)!
You have a nice RGB image. In a past tutorial, after creating the natural SHO image, you put the RGB starless image on top in Lighten blend mode. Would there be an advantage to adding that data here? It seems a shame to waste that data, especially for someone like me who lives in a Bortle 8 area. Just wondering what you think the best method is for adding the RGB to the narrowband data for these nebulae. Thanks!
Good question. It really depends on the target. The decision really centers on whether there are features that are only visible in the RGB data. Narrowband filters only record the ionized gas emission, so features like dust, IFN and reflection nebulae don't show up there. If the nebula includes those sorts of features then it's useful to add RGB detail to reveal those structures. M78 is a good example of a region that combines narrowband emission and reflection details. In this case, the Lagoon Nebula didn't really show any structures that were only visible in the RGB data.
Fantastic job, your working method is so different but oh so beautiful. Love it, thanks Craig.
Fantastic video Craig. Thanks so much for sharing your knowledge and expertise with the community!
Saving this for reference! Thank you.

Great tutorial Craig! Very informative and some valuable tips indeed.
