Focusing
The Ventana features a convenient center focusing knob.
However, because your eyes might differ slightly in their
focus, the binocular also includes a right eye diopter adjust-
ment. Follow this method for focusing: With both eyes open,
rotate the right eyepiece to the full counterclockwise position,
then sight on a distant subject. Cover the right objective (front)
lens with your hand (or simply close your right eye). Turn the
center focusing knob until the image in the left eyepiece is
sharp. Now uncover the right objective lens and cover the left
objective lens (or close your left eye, open your right eye).
Focus the right side by rotating the right eyepiece (do not
adjust the center focusing knob) until the image is sharp. The
binocular is now focused for your eyes. With the right eye-
piece now set, focusing is achieved solely by rotating the cen-
ter knob.
Rubber Eyeguards
The Ventana binocular’s rubber eyeguards allow easier posi-
tioning of the eyes for viewing while blocking some stray light.
When using the binocular without eyeglasses, we recom-
mend leaving the eyeguards in the extended (up) position.
For viewing with eyeglasses on, you’ll see more of the field of
view by folding them down. Merely press the rubber down on
one side of the eyeguard and then slide your finger around to
the opposite side while applying downward pressure.
