* 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
