This was taken at lake Rosset, 2.700 meters, Gran Paradiso National Park, on September 20th 2011, at 10:23 pm.
From left to right you can see: Piccolo Paradiso, Gran Paradiso, Tresenta, Ciarforon, Becca di Monciair, Denti del Broglio. Most visible in the night sky are obviously the Pleiades cluster and planet Jupiter.
The mirror works pretty well here, because water was quite still and the exposure was just 27 seconds, so not too long
