Hi Antonio
I did this workshop for fun, because as far as I understand, this is against the TOS rules ;-)
But look - maybe while taking your photo you could change the point of view and receive this composition?
In photoshop with lasso tool and feather 10 px I selected the moon and then separated into new layer. I moved this layer to a new position. With stamp tool I deleted the old position of the moon on base layer.
