Description

I was fortunate to have some success observing the transit of Mercury across the Sun today. There were high clouds throughout the day, but the transparency and seeing were markedly better during the last hour or so of the transit. This image was taken as Mercury approached third contact. Shot at high iso to keep the exposure short and freeze the atmospheric seeing.

Imaged with a C8 Evo, 2x barlow, and Nikon D750. Imaging train was configured to ~F/20. Single frame with 1/2500 sec at ISO-3200.
