Sure, we’ve all seen pictures of a space shuttle docking. But this one was taken from Earth using a fairly ordinary telescope guided by hand:
This remarkable picture was taken by Rob Bullen on Saturday February 26 from the UK, using an 8.5? telescope. I’ll note that’s relatively small as telescopes go! But the ISS is now over 100 meters long, and if it’s directly overhead (that is, the closest it can be to an observer on the ground) it appears large enough to easily look elongated in binoculars — in fact, it would be big enough to look elongated to someone with good eyesight and no aid at all*! Still, images like this are difficult to obtain even with a carefully guided telescope equipped with a video camera.
Oh — did I mention that Rob hand-guided his telescope for this shot?
