The two images which makes up this image had a small gap, so the middle part was missing. So I upscaled post #184817 to align the two images and fill in the missing part. However that image is completely in blue-scale and is shaded a bit different.
So I had to blur it a bit and then colorize it manually, but I'm not very good at it... If anyone wants to improve it and would like the layered Gimp file, give me a nod and I will send it to you.
