For those who have been living under a rock, that little dot on the upper right of the sun is Venus. The next time Venus will pass directly between the earth and the Sun will be in 105 years. The clouds were actually a blessing, allowing me to take these photos without any filters whatsoever. (I did use Live View to focus through the LCD rather than looking through the optical viewfinder.)
It's not often that you take a photo and realize that this is the only opportunity you'll have in your lifetime to shoot that subject.
