Cleaning Lenses
We recommend using the
Nightforce Cleaning Kit A130
to care for the lenses on your
spotting scope. The kit contains an
ultrasoft brush, microfiber cloth
and cleaning solution.
With the lens facing down to
allow the debris to fall away from the surface, remove loose dirt and dust
with a lens brush. Do NOT use high-pressure compressed air from cans (such
as found in office supply stores). They have been known to destroy lens
coatings. If there is grit stuck to the lens that won’t come off with a brush,
flushing the surface with alcohol or distilled water will prevent that grit from
being rubbed into the glass by the cleaning swabs.
Using a soft, clean, lint-free cotton swab or lens cleaning cloth, and lens
cleaning fluid applied to the swab, clean the lens starting in the center,
working to the outside in a circular motion. Make only one pass to the edge
where the glass meets the metal. Once you reach the edge of the lens, do
not re-use that swab as it will often contain abrasive grit that will scratch
the surface. Start over in the center with a new swab and repeat the process
until the glass is clean. Use a very small amount of cleaning solution for the
last pass to prevent streaks.
Store your spotting scope in a cool, dry, dust-free location.
Focusing the Image
While looking through the eyepiece,
slowly turn the focusing ring clockwise or
counter-clockwise until the image is sharp
and crisp. Closer images generally require
a counter-clockwise turn, while extremely
distant images generally require a
clockwise turn. You may need to readjust
your focus after changing magnification settings.
Rotational Axis Collar
When the TS-82™ is mounted on a
tripod, there may be times when you
want to rotate the spotting scope
to acheive a more comfortable or
suitable viewing position. Loosen the
indexing knob on the Rotational Axis
Collar by turning it counter-clockwise.
You can then grasp the spotting scope
body and turn the entire scope up to 360 degrees. Tighten the knob to hold
the spotting scope in the new position.
Do not overtighten the knob.
The
Rotational Axis Collar allows you to make adjustments in viewing position
without having to remove the scope from the tripod.
Caring for Your Spotting Scope
All Nightforce spotting scopes are 100% water-proof, dust-proof, fog-
proof and purged with inert nitrogen gas to prevent condensation from
accumulating on optical surfaces. Nevertheless, like any fine optical
instrument, it is necessary to carefully handle and protect all optical surfaces
from damage. When the scope is not being used, the objective and eyepiece
lenses should be covered by the protective caps which are provided.
Never use gun cleaning solvents, aerosols, other harsh solvents or chemicals,
cans of compressed air or insect repellants around your spotting scope or
another other optics with coated lenses, as these can ruin the coatings applied
to the glass surfaces.
Cleaning the Spotting Scope Exterior
Clean the scope’s body with a clean cloth lightly moistened with clean water
or alcohol. Do not use strong solvents. While cleaning your scope, be sure to
protect its lenses by installing the covers that came with it. Ammonia-based
solvents can destroy the coating on the glass.
In the event of submersion in mud, sand, dirty or salt water, flush the outside
of the scope with clean water to remove encrusted material and salt. Install
the lens covers before flushing with water. Wipe the outside metal surfaces
dry with a soft cloth then proceed to the step below.
Using the TS-82
™
for Photography
The Nightforce TS-82™ can produce spectacular photography of distant
objects. The optional A276 for the iPhone® 4/4S or A277 for the iPhone® 5
allow you to attach your iPhone to the eyepiece and capture
excellent high-resolution images and/or videos. There are also third-party
mounts available that will accept many point-and-shoot and DSLR cameras.
