    Oh sure.. NOW I see this message..
    I *only* track the stars on a motorized equatorial mount..
    Satellite trails are quite visible, including Geosats..
    I can send you all the images of mine you wish to test, especially since I
    do not acquire too many a night.. (Yet!)
    It sure worked well on the one you did already.
