A nice selection. I guess all these cloudy nights have a use (of sorts). ;)

They keep me busy if it clears after midnight! That's when all the shots for this one were taken. 12 to 3/4/5AM.

Roberto,

Great images well done.
Also did you know that the phrase used ' Siamese twins ' is not really correct.
Although the conjouned twins were first discovered swimming in a canal in Thailand which was at the time Siam, the twins were actually Chinese origin !!
Any way great images
