Duncan, Rich, David
many thanks for your warm welcome and thanks for the kudos.
As you might have seen, I have already a few images posted on my website.
So I would say I am not completly unexperienced, but still novice who is getting better.
David,
i tried to make a compromise between most detailed and pretty picture.
I saw when I try more the noise is getting to much.
But I would love to see when you want to try it. I can give you the stacked and crude image as 16bit-tif.
Theres only one deal: You have to explain me what you have done. Thats for me to improve my skills in the image processing.
Again, thank you all.
