Very good seeing condition, all shots were taken in Zola Predosa, near my personal observatory, BUT on the side of the hill overlooking the plain. This confirm me that my usual position is affected by bad seeing.
Finally, I’ve found what I’m searching for. The perfect night! It’s a long time since I’ve searched for it, clear sky, during the focus procedure I’ve noticed that it was easy. Lots of details during the film. That night payed the effort of the entire journey.
