Description

I was fortunate to have some success observing the transit of Mercury across the Sun today. The morning started out with thin high clouds, but I was able to observe the start of the transit starting just after first contact. This image was taken as Mercury approached third contact. High clouds dissipated somewhat and the atmospheric seeing was much improved over my early morning shots when the sun was close to the horizon.

Imaged with a C8 Evo and Nikon D750. Imaging train was configured to give me ~F/10. Single unprocessed frame with 1/640 sec at ISO-100.
