This photo is taken by one of dh's partners who is an amateur astronomer. The small (pin tip size) black spot at the middle/bottom right is Mercury. The larger black spot on the far right is a sun spot. There are also two smaller sun spots along the edge on the left.
Even though it's a pain, I'm going to keep this photo big for a little bit so you can actually see Mercury. On the smaller size you couldn't really see the pin point. I'll change it back to normal in a couple of days.
