Doesn't look real to me. Here is one of venus transiting the sun in the summer. FWIW...none of us will see this happen again. Its not do to occur again in our lifetimes.
You have a point woollybear -- it does look a bit suspicious. Maybe a crop from an image taken with a 6" refractor? Maybe not. OP has yet to pipe up with any specifics.
BTW - nice shot of Venus's transit.
The last transit of Mercury occurred on November 8, 9 2006. The next transit of Mercury is due to occur on
May 9, 2016.
