Oliver Stiehler, a German astronomy amateur, achieved his fame in this community with a stunning ISS image back in July 2008. As a matter of fact, he has been witnessing the construction of International Space Station since beginning of 2007.
The following pictures were taken by Oliver in March 2009 with the DMK 21AF04.AS, a great astronomy camera manufactured by The Imaging Source.
if you look at the third picture carefully enough, you might notice a light gray, human shaped shadow on the right side of ISS. At first Oliver thought this shadow could be a space walking astronaut. But the next day he sent us another e-mail to refute that assumption with a 3-D model of ISS:
