    This post is for anyone interested in learning how one person recently shot
    spectacular images of the orbiting ISS.
    The technique is used by Dave Cash and is featured at
    I just obtained more detailed information via a personal e-mail and am
    sharing it here.
    [Dave taped a wooden stick to his scope to aid his manual  tracking. The
    webcam that he uses blocks his view of what he is shooting so he simply
    lines the ISS up in the cross hairs of a finder and hopes he gets it!]
    Dave replied........"To answer your questions:
    The wooden stick was an improvisation "in the field" to try to
    get better and finer control over the pointing of the scope. The stick is
    about 2 or 3 foot long and is taped to the front and back of the scope tube
    above the declination bearing. About 1 foot or so projects back behind the
    mirror cell to act as a kind of lever.  I was quite surprised at how well it
    seemed to work.
    What you do is make sure that the scope and finder are well aligned. You
    need to make sure that when a bright star is centered on the finder cross
    hairs that it's image is centered in the PC webcam preview window.  Once the
    ISS is sighted with the naked eye, start the webcam recording and then try
    to keep it's image centered on the finder cross hairs by using the lever to
    track it.  Most of the time the ISS never makes it into the field of view
    but if you are lucky you may bet a few good frames that show it !!!  I tend
    to get about 1000 frames in my AVI's but only about 20 frames show the ISS,
    and of those only a few are sharp enough to show details.  Still it's worth
    If you need any more information then please let me know
    Best wishes
