    You haven't lived until you're tracking a satellite in your 10x50s and a bat 
    flying towards you enters your FOV.
    One last note on HST visibility - I've had accasions where the HST was not 
    visible (dimmer than +6.0) and other passes that were briefly -2 mag (at 
    least).  The range of the HST is always about the same: ~1000 miles or 1600 
    km.  The orientaion rather than the range seems to affect its brightness more.
