OK, I have color. Getting there, but not quite happy with the result. This is my first attempt at LLRGB layering to assemble the color and luminance data.
Too much noise and structural information is coming through with the color data. I had to use a lot of noise reduction in final processing.
Some odd rectangular structure around bright stars that might be coming from the microlenses of the CMOS sensor. This shows in the color data, but not so much the luminance.
Still have some learning to do…
