    Like Tony, I have used 7*50 for the last 36 years, and I agree with him
    about field-of-view.
    But it also depends on what you want to see (in addition to faint

    my time finding and observing the satellites, instead of predictions,
    notes, star maps... and the star fields where the satellite is expected.
    If you want to "hop" between many geostationaries in a short time, or

    satellites that have maneuvred by scanning the orbit plane, or satellites
    that are faint for long periods between flashes, you may make the same
