Thierry Legault has a long history of great captures of the ISS, and not only that, I remember having seen lots of images from him on Spaceweather.com, also of the chinese Tiangong and even of the Shuttle when it still docked to the ISS...seeing this last one, he definitely improved an already impressive technique (and equipment).
Trying to catch the ISS in a telescope while flying overhead at 28.000 km/h is as fun as it's tricky...I enjoyed it several times on direct viewing from my 4" mak-cass, relatively easy to do after a bit of practice and you can really appreciate the shape of the station while it rotates and fades out of view...tried a couple times to capture it on video/photo and well, that's an entirely different business. Let's say the result has been rather underwhelming.
