Space Station Crosses the Sun

The International Space Station is seen crossing in front of the solar disk in this image. This transit took about 0.53 seconds, so don't blink! This was captured with a Canon 1DC in 4K video mode at 24 frames per second and every frame that had an image of the ISS was stacked to give the final composite image. A 800mm Canon f/5.6 lens was used with a 2X tele-extender and a mylar solar filter. A sun spot cluster is visible on the upper portion of the solar disk. The CalSky website was used to predict the location for and the time of the crossing.
