Here are some images from the Venus transit, which occurred on June 5, 2012. These were taken from Santa Ana, CA on the top level of a parking structure. I used my Canon 1D M4 with a 100-400mm at 400mm and a 1.4x which gave me a focal length of  560mm, these are crops of the image, taken using a solar filter. You can see several sunspots in addition to Venus as it moved across the face of the sun. These were taken over a period of about 3 hours. Hope you enjoy them, click on the images to see larger versions.
