>From our vantage point on Earth, it takes just a half second for the International Space Station to fly across the face of the Moon, so catching a transit is tricky. But award-winning French astrophotographer Theirry Legault captured an amazingly sharp and detailed transit image that makes the ISS look like it is sitting on the Moon’s surface! Legault took this image from Avranches (Normandy, France) a few hours before the eclipse, on December 20th at 21:34 UT. He used a Meade 10? ACF on Takahashi EM400, with a Canon 5D mark II. The transit duration was just 0.55 seconds, as the ISS is traveling at 7.5km/s or 28,0000 km/h (17,500 mph). See below for a close-up crop of the image which shows the amount of detail visible of the space station.
