Been studying layers ever since the AstroGeek explained that they were necessary for some astro image processing. I'm not yet ready to tackle the Trapezium but I've been messing around with various tutorials and some of it's getting thru.
Always wondered how my RGB lunar images come out monochrome while there are some stunning color lunar images posted online. Well, there's tutorials for that too.
Luna in technicolor
Re: Luna in technicolor
Wow, Pete, this is fantastic!!
I even looked at it magnified at 3000 x 2024 px
Nice work.

Beautiful, Pete. Subtle warm & cool grays and tints make this very pleasing to look at.

Thanks to you Geek 
The colors are really there but must be saturated in post processing to bring them out. Supposedly they're associated with different minerals in different location. Need to research this.

Researched this. The Moon Is Not Black And White, It Just Looks That Way.
Hands up if you think about the Moon in black and white? Yes - well, you're not alone, and there's actually good reason for you to, because the surface of the Moon is nearly devoid of strong colors in comparison to what we're used to here on Earth.
The appearance of the moon is the representation of the minerals that make it up. For the most part, the Moon is grey because plenty of oxygen, silicon, magnesium, iron, calcium, and aluminum are on its surface. The proportion of other elements that do have color is very low , so while the moon has various faint colors it appears gray to the eye.
We can’t see the actual color from the surface of Earth because they are faint and our atmosphere partially filters or blocks various wavelengths of light reaching us. This happens because of the scattering of shorter wavelengths of light by our atmosphere.
Visually the moon appears gray when high in the sky. When it is low, rays passing through thicker atmosphere cause the shorter rays to be scattered, and the Moon appears yellow. This image has been processed so as to eliminate atmospheric effects while increasing color saturation to the point where the true colors are visible.
