(3) When the stage is rotated, the detail moves in circle †. Manipulate

the two stage centering knobs ‡ to coincide the imaginary center of

the circle † circumscribed by the detail with the intersection of the

eyepiece cross lines.

(4) Moving the specimen only, move a new specimen detail into the

cross line center.

}Repeat steps (3) and (4) several times until the center of the stage

rotation is in the center of the cross lines, i.e., when rotating the stage,

the specimen stays in the center of the cross lines.
