I was a bit disappointed by the original version. So I had a look more acurately on the raws. In fact many were not good and affected by a poor follow up (reason: strong wind or a facetious cat in the garden playing with the different cables under the mount...?) I decided thereby to keep only 12 on the 51, and stack with drizzlex2 option.

Cropping and more contrast….not obvious the best one…!
