Corona from Svalbard
This image is the composition of 29 eclipse images acquired by means of 800 mm lens and Nikon D810
camera. Even though the Sun was only about 11° above the horizon it was possible to visualize
not only the solar corona in good contrast and high resolution but even the lunar surface
surprisingly well. The position of the Moon represents the situation 8 seconds after the second contact.
