About this image

A montage of images of the ISS covering an interval of about 18 seconds, beginning just after the lunar transit seen from my location. The sequence runs from right to left, and shows the changing appearance of the ISS and its solar arrays as the angle of view changes. The middle image of the sequence is also shown at 2x scale. Each image is a stack of between 45 and 60 frames, processed in PIPP and Registax. This was a more oblique view of the ISS than an overhead pass, which gives a better impression of the 3-dimensional structure of the station.

Astonishing image Chris. Try relaxing your eyes to see ISS in 3D using sequential images. Amazing.

That's a great idea, Steve, and I can't think why it didn't occur to me! There are two methods for viewing image pairs in stereo, so-called "cross-eyed" and "wide-eyed", and most people seem to use cross-eyed, but I've never been able to make it work, so I always use the wide-eyed technique. These images are in the correct relative positions for cross-eyed viewing. I think I'll put together another post with image pairs in both positions, so anyone who knows how can see the 3D effect.

Have my red / cyan glasses ready. If you want to email me your L/R images I can adjust colour and combine them into one image.
