The transit of Mercury 2016.

A Mercury transit only happens about 13 or 14 times per century, so this is the first time I have had an apportunity to photograph it. In Denmark the transit took place from 13:12 to 20:42, and since summer has just arrived the sky was clear and the Sun had no intention of setting before the end of the transit. I was not sure if my cheap 300mm zoom lens was good enough to detect the shadow of Mercury, but it managed just fine. I took a few shots every hour starting from 13:30 and during the peak at 16:57, I did miss the final one at 20:30 because the Sun was hiding below the city skyline. I am very happy about the resutling combined photo which clearly shows the path of Mercury (from left to right) across the Sun as well as a rather large group of Sun spots.
