Mercury is on the extreme right while the centre blob is a sunspot. 1/1250 sec at ISO 200 through a Canon 70D and an 80 mm Skywatcher Equinox refactor. This was within 2 minutes of the egress of Mercury which I missed photographically with a human or mechanical error. But I saw the egress in a large Dob and it was quite a sight as the little nick in the sun, Mercury, slowly disappeared. What a sight!
