    Sorry, the question was both poorly stated and already included in the data
    you posted.

    My point being, there are some positions that give me fits. Getting a good
    shot is extremely difficult for me. Could we located other stars in the the
    same separation range as the problem areas that might offer a different
    (easier) sextant position?
