As objective magnification increases (leading to a much smaller **field** **of** **view**), the discrepancy between the **field** **of** **view** center and the axis of rotation becomes greater. At the highest magnifications (60x and 100x), even minute errors in centration can lead to huge differences in specimen placement as the stage is rotated.
