3-6 Eyepiece Adjustment

Eyepiece adjustment

The eyepiece adjustment is performed before
target sighting.
qRemove the telescope lens cap.
wPoint the telescope at a bright object, and rotate
the eyepiece ring full counter-clockwise.
eLook through the eyepiece, and rotate the
eyepiece ring clockwise until the reticle appears
as its maximum sharpness.
●When looking into the eyepiece, avoid an intense look to prevent parallax and
eye fatigue.
●When it is hard to see the reticle due to poor brightness, press [ILLU] to
illuminate it . For adjusting intensity of brightness, refer to page 35.
