It was not a good capture. Accustomed, now, with the facilities of the guiding I left the camera capturing and went to my bar drink coffee. Law of Murph: I took so much time to obtain a good focus that the battery was out. What was to be a 1 hour of capture was transformed in 20 minutes.
There is no version of wide scale since the sign came very weakly I had to pull very much in the treatment, leaving an impression artifical in the image. Reduced, hide a little the cosmetic !
