User manual ORION TELESCOPES & BINOCULARS BINOS

[. . . ] Binocular Instructions Warning: Never look at the Sun with binoculars or any other optics. To use any Orion® binoculars, simply adjust the distance between the binocular halves to fit your eyes, and turn the center focus wheel until the image is sharp. For more details, read on. Roll-Down Eyecups Most Orion binoculars feature roll-down eyecups. [. . . ] On larger lenses, clean only a small area at a time, using new tissue each time. On excessively dirty lenses, wipe across using one stroke for each tissue, alternating wet and dry. The more fresh, clean lens tissue you use, the less likely you are to scratch your lenses. It is better to leave a tiny amount of dirt on the lens than to use too much pressure and destroy the coatings. Eyecups in the "eye-up" position Eyecups in the "eye-down" position Adjusting the Distance Between Your Eyes Hold each barrel firmly and move the two barrels together to match the distance between your eyes. Make this adjustment before you focus. Focusing The small center wheel between the two barrels is for focusing the binoculars. The rotating right eyepiece is called the diopter adjustment. Diopter Adjustment Because all eyes are slightly different, Orion binoculars feature a "Right Eye Diopter Adjustment. " The purpose of this is to compensate for slight differences between a person's two eyes. With both eyes open, cover the right objective lens (front) with your hand. Turn the center-focusing wheel until the image in the left side is sharp. Again, cover the left objective lens (front) with your hand and focus the right side by rotating the right eyepiece until the image is sharp. Make a note of the diopter adjustment and turn the right eyepiece to that diopter adjustment whenever you look through them. Once you make this adjustment, you do not have to touch the diopter adjustment. Simply focus both sides by turning the center wheel. Storage and Cold Weather All optics, when exposed to excessive temperature changes or high humidity, have the potential to fog up. Always allow the optics to slowly adjust to cold weather by storing the instrument (in its case) in a cold area such as an unheated garage or the trunk of a car for a few hours before use. When bringing the instrument back inside a warm house, store it in a cool area for one to two hours. It is very important to then open up the case, remove the instrument, then remove the caps, and let everything dry out overnight. The instrument should be stored in a cool dry place; storing it in a moist environment will result in mold growth and destroy the optics. [. . . ] Binocular collimation (alignment of the two barrels) is specifically not covered beyond the 30-day return period. Binocular collimation (and cleaning) are considered routine maintenance and should be done every five years, or when necessary. Charges usually start at $35.
