Rotating Earth on the Bottom of a Crater

Region: Europe

Site: Nisyros - ‎Greece

From the photographer: "A trip to Nisyros Island in the southeastern Aegean resulted this 355-minute startrail image. The island is best known for being the remnant of an active volcano with four major outbursts in the past 150,000 years. The stunning caldera is characterized by this 300-meter wide and 27-meter deep crater, named Stefanos, at its dead center. I employed my Peleng 8mm circular fisheye lens so as to try and get as much of the crater periphery as possible. Since my lens is slightly soft at its native f3.5, I purposely stopped down to f8 and I was delighted with the sharpness from one edge to the other. There were very strong winds all evening and I had serious worries as morning approached that I would find the camera and tripod baking in the sulfuric acid at the floor of the crater. Examination of the individual 120-second sub-exposures revealed that the wind gusts did move the tripod sufficiently to mess up the continuity of my star trails, but just 20 minutes prior to the end of my 6-hour planned session."
