When I was in the Vignemale area in the French Pyrenees, I went up with two cameras and two lenses. One of the equipment, I left it shooting more than 5 hours at night to capture the movement of the stars and take a Startrail, this was the result.
Sky: 640 shots of 30 seconds.
Land: Blue Hour 30 seconds, f8 Iso 640.
