The clarity that Czech photographer Miloslav Druckmüller from the Brno University of Technology, managed to get of this stunning solar corona was due to the 47 different images, shot on two different lenses, that he composited to make this singular image.
The detail and contour of the image also owes a lot the lack of light pollution at the extremely remote Enewetak Radiological Observatory on the Marshall Islands, in the middle of the Pacific Ocean, where he shot them.
