Transit of Mercury


Tom Howard

Crawley, Sussex

Nikon D7000 DSLR, Nikon TC-20E teleconverter, Meade 5000 127mm refractor, Skywatcher AZ-EQ6 mount.

Conditions were far from ideal in the south of England, but I managed to take this shot of the transit shortly after second contact. What struck me most was that the sunspots were not black when compared with the silhouette of Mercury, which is seen as a complete absence of light.
