Observation Using Eyeglasses
Fold the eye shades to prevent damage due to contact between the
eyeglasses and eyepiece lenses.
Observation Without Using Eyeglasses
Extend the eye shades in the direction of the arrows to facilitate
observation by preventing penetration of incident light through the
space between the eyes and eyepiece lenses.
