I have both a sky vector and a jmi and have lived thru about all the
problems that can be. on the lumicon, caster and aldeberon are to close,
try, capella and deneb, or much later in the evening, capella and rigel.
also do not do to close to the horizon it messes up the algorithms,.
before you do anything make sure there is no sticking, do an encoder
test in both alt and az, if it still does not work, call lumicon tech
support , john has been most helpful to me,
clear skies,
