to the center of the field of view.
Be sure to adjust the stand height.
If the stand height is not adjusted, following phenomena may
appear.
· The periphery areas of the field of view of the assistant
observer are cut off.
· The deviation in the field of view occurs between the main
observer and the assistant observer.
· The field of view of the assistant observer is colored.
The farther away from the center of the system you apply
the force to the observation tube, the larger the force to be
applied to the entire system becomes. Do not apply the
excess force on the observation tube carelessly.
