Mercury Transit 2016 Double Exposure

The Transit Of Mercury

    The orbits of Mercury and Earth lined up in such a way on May 9, 2016 that Mercury swept directly between the sun and us. From sunrise until just after lunch, those of us with the optics and equipment were able to watch Mercury, as a small black spot, move from one side of the sun to the other. For you photographers out there my settings for shooting the sun were: 1/4000th of a second, f/32, 100 ISO with a 10 stop neutral density filter attached to a 200mm lens. The photo above has two images taken that day, separated by just over two hours of time. Mercury is the lower of the two black spots you see on the sun. For all you fact checkers and history loggers, the left one was taken at 8:20am and the other at 10:36am Mountain time, from just outside Denver, CO. Cheers!
