OK le tirage n’est pas le m\u00eame, mais en premi\u00e8re approche j’imagine que les faisceaux doivent arriver le plus parall\u00e8le possible dans le blocking filter. R\u00e9sultats:
\nGauche: Blocking Filter -> Barlow

Chaque image est s\u00e9lectionn\u00e9e parmi une s\u00e9rie de 8 captures; la mise au point a \u00e9t\u00e9 r\u00e9ajust\u00e9e \u00e0 chaque capture, afin de minimiser le risque d’impr\u00e9cision de mise au point.<\/p>\n

Ma pr\u00e9f\u00e9rence va pour le montage de droite. Votre avis?<\/p>\n
