Roll-Down Eyecups

Orion Astro-Binoculars feature fold-down eyeguards. The eye- guards are usually left in the up position for use without eyeglass- es, as this helps prevent glare (unwanted stray light) from enter- ing between your eye and the eyepieces. To use the binoculars with eyeglasses, you will need to fold the eyeguards down in order to get your eyes close enough to the eyepieces to see the entire field of view.

Cleaning and Care of Binoculars

The lens surfaces of Orion binoculars are coated with anti-reflec- tion coatings that can be damaged with careless handling. Avoid touching lens surfaces with fingers or any coarse material. All optics, even if stored, should be cleaned at least once a year or whenever they are dirty. The dust that builds up on coatings pro- motes mold growth, which etches glass and destroys coatings. Avoid over-cleaning; it can damage the coatings. Always use lens cleaning tissue and fluid that are specifically designed for multi- coated lenses. Do not use fluids or tissues that are for eyeglasses or household use.

To clean the binocular lenses, first blow off the lens with a blower bulb or gently wipe the lens with a lens cleaning brush to remove the larger particles. Put a few drops of lens cleaning fluid on a fresh piece of lens cleaning tissue (never on the lens) and gen- tly wipe the lens. Quickly wipe the excess fluid with a new, dry piece of lens cleaning tissue. For larger lenses, clean only a small area at a time, using a new tissue each time. On excessively dirty lenses, wipe across the lens using one stroke for each tissue, alternating wet and dry. Always avoid excessive pressure or rub- bing when wiping, as wiping too hard can scratch the lens.

Storage and Cold Weather

Orion Astro-Binoculars come with a soft case for storage and transport. We recommend always keeping the binoculars in their case with the cover caps on when not in use.

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 open up the case, remove the binoculars from the case, remove the cover caps, and let everything dry out overnight. The binoculars should be stored in a cool, dry place to prevent mold growth, which can damage the optics. This is not covered by the warranty.
