ther enhanced by color filters such as light blue, yellow, or red,
and the classic Moon filter to block excessive glare. Since the
BinoViewer works best for brighter objects, a light pollution
filter may only work on the brightest deep space objects. A
broadband filter, such as the Orion SkyGlow, may improve the
contrast and eliminate distracting haze from city lights.
The barlow lens also accepts filters. Simply thread them onto the
front of the barlow lens when it is installed on the BinoViewer.
solar observing
Your BinoViewer reveals copious detail on our nearest star,
the Sun. A white light solar filter placed on the front aperture of
your telescope will provide a safe view of the Sun accentuated
by the BinoViewer. These views are best enjoyed at medium
power, from 50 to 100x.
storage
Although your BinoViewer is durable, it should avoid prolonged,
unnecessary exposure to the elements. Keep the BinoViewer
in its case, with caps on when not in use. It is also recom-
mended to leave the BinoViewer in a dry place with caps off
and case open overnight to let it completely dry out.
Store the instrument in a cool, dry place; storage in a humid
environment will result in mold growth on the exterior of the
prisms that can destroy optical coatings. This is not covered
by the warranty.
cleaning
The prisms of the BinoViewer and lenses of the 2x barlow
lens are coated with anti-reflection coatings, which can be
damaged with careless handling. Avoid touching prism or lens
surfaces with your fingers or any coarse material. Clean the
prisms and lens surfaces if they get noticeably dirty. Always
use lens cleaning tissue and fluid specifically designed for
telescope optical coatings. Do not use regular tissue or fluids
made for eyeglasses or household use. Do not disassemble
the BinoViewer to clean it, with the exception of the chrome
barrel, which may be unscrewed to better access the forward
prism surface.
To clean the prism and lens surfaces, first blow air on the sur-
face with a blower bulb or compressed air to remove any large
particles. Then brush the surface with a soft lens brush and
blow air on it again to remove any dislodged particles. Put two
drops of lens cleaning fluid on a sheet of lens tissue; never put
lens cleaning fluid directly onto the prism or lens. Wipe the sur-
face gently with a circular motion, taking care to avoid undue
pressure or rubbing, which can scratch the coatings. Quickly
remove the excess fluid by wiping with a clean, dry lens tissue.
