    I recommend getting the widest-field eyepiece that you can get (shoot for
    a theoretical 1 degree-wide field or larger).  With my 10mm eyepiece
    coupled with a 2x barlow (thus, effectively 5mm), it is hard enough to
    just get Jupiter or Venus in sight after aligning the telescope with a
    finder scope.  Whenever I try to track satellites, I do it with a 26mm
    eyepiece, that produces a theoretical 61' wide field (though, in
    actuality, it's more like 50').  It's still extremely difficult to track
    satellites with it.  I've learned by experience that it is easiest to
    acquire the satellite at lower elevations (which is when it travels at
    the lowest angular velocities).  It takes awhile to get good at it (and I
    haven't yet).  Practice with planes, they travel at about the same speed,
    unless you've been blessed by living in a desolate place .
    I was watching CNN, and Miles O'Brien was reporting live.  The usual
    weekday afternoons dark-haired woman was at the 'desk' (for lack of a
    better term), and she sounded like it was by some miraculous technology
    of the new solar panels that you could actually GLIMPSE the ISS !!!!! 
    Like that was something new, and that you couldn't see the ISS until the
    new solar panels were attached !!!
    Once all these misconceptions and misinformations stop, then maybe the
    cable networks will *consider* carrying NASA TV.  If NASA TV existed
    30-35 years ago, it probably would have received some of the highest
    ratings on TV.  Now, most people wouldn't care.
