Adjusting the pupil distance
Adjust the positioning of the eyepiece lens
- The height of the eyepiece can be selected in two ways, upper and lower, so adjust the interpupillary distance at the position that is easier to observe.
Adjust the left and right field of view into one
- To avoid fatigue, adjust the space between the left and right eyepieces to your face.
- Look through the eyepieces, overlap the left and right fields of view to one.
