Why so many Darks, i have always heard and thought that anything over 16 you dont gain anything more in calibration , interested to see an image with 16 Darks to compare.

Nice image, either way.

Dark trees also bring their noise to the photo and the more of them, the more averaged noise is and they contribute less.
