* When use 0.5X auxiliary objective, the focus arm should be changed to upper position of the square rail pillar
stand.
◎
No matter the zoom magnification, the working distance of same objective will not change.
◎
Use the following formula to calculate Total magnification and field of view
Total magnification = Zoom Magnification × Eyepiece Magnification × Auxiliary Objective Magnification
FOV=Eyepiece FOV / (Zoom Magnification× Auxiliary Objective Magnification*)
* Without Auxiliary Objective, this value is 1
