8x27 WP Binocular

Congratulations on your purchase of a precision Orion binoc­ular . This rugged, ergonomically-designed compact binocular
is nitrogen-purged and sealed to be completely fogproof and
waterproof. It features a slightly larger aperture than a typical
binocular of its class, for brighter images, while maintaining a
light weight. You’ll find the Ventana an excellent companion
for birding, sailing, camping, kayaking, or other outdoor pur­suits. With proper care and use, it will provide many years of
superb, enjoyable viewing. To get the most from your binoc­ular, please read all of the following instructions.

Warning: Never look at the Sun with binoculars or any
other optical instrument! Severe and permanent eye dam­age could result. On sunny days, children should use this
binocular only with adult supervision.

Adjusting for the Distance
Between Your Eyes

The distance between the eyepiece lenses of the binocu­lar should be adjusted to match the distance between your
eyes, called the “interpupillary distance.” To adjust the
binocular, hold each barrel firmly; move them together or
apart while looking through the binocular with both eyes
until you see a single, round field. Make this adjustment
before focusing.

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 adjust­ment. 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 eye­piece now set, focusing is achieved solely by rotating the cen­ter knob.

Rubber Eyeguards

The Ventana binocular’s rubber eyeguards allow easier posi­tioning of the eyes for viewing while blocking some stray light.
When using the binocular without eyeglasses, we recom­mend 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.
