    For what it's worth, as we have been observing and attempting to
    photograph Mir for many months now (@ 40X with an 8" reflector), see:

    It is possible to see some detail, Mir can look like a tiny L or T or
    H... but David is right, the glare is tremendous at culmination, I
    usually look for structure in the second half of a pass, as the object
    gets lower in the sky and the apparent motion slows and the glare
    retreats somewhat, set the scope ahead of the path of the object, let it
    settle for a second and look carefully as the object cruises through the
    feild of view... you could get lucky. It probably helps to try it a few
    dozen times.
    
    I recently purchased a pair of Celestron 20 X 80 Binocs (yay!), and
    tried the above approach (with binocs on a tripod), and was treated to a
    tiny golden "cross" as Mir skimmed off into a light cloud cover. Fun!
