This is the second time that I try to take IC 2118: The witch head

The first time I had little experience and the exposure time was highly inadequate.
This time I was betrayed by the wind with a gust up to 150 km/h has moved the camera bringing the subject off center.

Let's hope in the third!

Questa è la seconda volta che provo a fotografare IC 2118: la testa di strega.

La prima volta avevo poca esperienza e il tempo di posa è stato fortemente inadeguato.
Questa volta sono stato tradito dal vento che, con una raffica a 150km/h, ha spostato la camera portando il soggetto fuori centro.

Speriamo nella terza!
