Zoom adjustment
The eyepiece adjusting wheel is a variable magnification hand wheel, the adjustment range is 10-30 precision, counterclockwise to increase the multiplier, clockwise to adjust the small multiplier. Note that the zooming process should be adjusted slowly, not too fast. After the multiple is changed, the focus needs to be adjusted again, which is to operate the third step again. (Remember that the process needs to be adjusted slowly, only precise focusing can achieve the desired effect)
