Not quite de ja vu... but I just posted a thread about imaging satellites as well - coincidence!
I saw an article back in the late 80's, I think in an edition of "Astronomy", where guys there were using fork mounted C8s with huge (by today's standards) video cameras hanging off the back of them. I can't remember the details, but I have in my mind that they had some sort of custom built drives on the mounts to move the scopes quick anough to track, and they were tracking the satellites to video them.
I have thought about some hair-brained schemes to have a go at it, but not sure what would work... maybe a dob, toucam, laser pointer combination with really good hand eye coordination???
