 Hi Robin,

    Yes I have checked in all directions and found no shift at all in the lines. There is a slight shift when using the motor to focus (much the same as if I were manually focusing) but this can be reduced as I stated earlier by adjusting the tension of the screw on the collimator body support opposite to the motor,once the unit is focused everything is stable.
