I haven't as of yet - I've just tracked some of the smaller sats. I've only done the satellite tracking (so far) at work. The skies have been so crummy this winter that we haven't been able to do much. We tried to track and image it the last time the shuttle was docked with ISS. But, it was shortly after dusk - so we didn't have a really good alignment - so we ended up chasing it across the sky. We were planning on imaging ISS with the shuttle in March - but obviously the plans have changed. . Here is a link to some others that HAVE imaged ISS, plus I think there was an article in Astronomy or Sky & Tel fairly recently. They got quite a lot of detail.
