phase annuli will not be able to hold an acceptable
alignment due to variations in objective indexing.
The other problem that may be seen is caused by
overall float of the revolving turret, relative to the
center point of the stationary base. If there is excess
play in the center-pivot ball, such that the turret is not
held in the exact center point, the whole turret may
move slightly, resulting in poor objective centering and
all that that entails. This problem may be encountered
if the threaded retaining ring has not been properly
snugged down, or if the center pivot-adjustment screw
has not been properly adjusted to remove the play in
the center-pivot mechanism.
