Axial Adjustment for Cameras with Tripod Mount under the Lens Axis
If your camera has a tripod mount at correct position, i.e., under the lens axis, you can
simply use the EPDM adapter if you tripod mount lies within the range of axial adjustment.
Note that the horizontal adjustment is affected by the choice of the adapter in use.
On the adapter, there are white marks that correspond to the center of tripod mount. So
you simply mount your camera on it and adjust its position so that the white mark corresponds
to the distance of the tripod mount from the entrance pupil position.
Check that the lens axis is parallel to the vertical rotator arm then tighten the knob.
Check if the whole assembly is leveled. Then you can start taking photos at various angles of
elevation and rotation.
If you need to extend the range of the axial adjustment, you must use the off-axial adapter.
Depending on which side of the range you want to extend, you can mount the off-axial adapter
in 2 orientations.
