Not so much progress on the noise side - I tried to reduce chroma noise with an option in UFRaw. The result is, well, see yourself in the image above (200% view).

1 - the noisy image

2 - the denoised image

3 - the denoised image with chroma noise reduction

4 - 1 and 3 combined with a mask for the edges.

I’ll explore soe more noise reduction options before I finish this image.

In the main part of this video you’ll see how to register an additional image into the already rotated and cropped  stack of layers.
