Naked eye
Binoculars can open up a whole range of new and exciting impressions
when travelling on holiday, taken to sporting and leisure events or used as
part of a hobby such as birdwatching or astronomy. To help you get the best
results from your equipment please read the following instructions carefully.
Adjusting to obtain a single picture. To adjust to the spacing of your eyes
simply rotate the two sides of the binocular around the centre hinge until a
single rounded picture is obtained when looking through both eyepieces.
Adjusting for maximum sharpness. Many people have slightly different
vision between their eyes. When using binoculars, this difference can be
compensated for by turning the dioptre adjustment ring located on the right
eyepiece tube.
To set the binoculars correctly, close your right eye and look through the
left eyepiece with your left eye and using the centre focus wheel - focus on
an object of your choice until it is clear and sharp. Next, close your left eye
and look through the right eyepiece with your right eye. You may find the
object being viewed is not absolutely sharp and this can be corrected by
rotating the dioptre adjustment ring (but without turning the centre focus
wheel) until the object being viewed becomes sharp. The binoculars are
now set and a perfectly clear and sharp image should be attainable when
using both eyes together. To focus at different distances simply turn the
centre focus wheel.
User Instructions
Retractable rubber eyecups and wearing glasses. Opticron Aurora BGA
binoculars provide the full field of view when wearing glasses. To get
the maximum field of view with glasses on, turn the eyecup clockwise
into the ‘down’ position. Remember to return them to the upright
position if you or anybody else wants to use them without glasses.
Care and cleaning. Binoculars require little maintenance but
occasionally the outside surfaces of the eyepieces and objective lenses
will need cleaning. To avoid damaging these surfaces please read the following carefully.
(i) Gently remove excess dirt and dust using compressed air or blower brush.
Caution: Hard and persistent rubbing of dirty surfaces can cause abrasive scratches on the surface of the glass
which may distort viewing.
(ii) Breathe on exposed glass surface and then wipe with an optical cleaning cloth (code 30277) in a circular motion
until the surface is clean again.
Do not attempt to dismantle the instrument as this will invalidate the guarantee.
Cold weather. In cold weather the external lens surfaces may steam up when moving the instrument from cooler air
outside to warmer air inside. If this happens, leave the instrument to stand for a few minutes until any condensation
evaporates.
WARNING Never under any circumstances use a binocular to view the Sun. Doing so may cause serious damage to
your eyes.
We hope you will get a great deal of pleasure from your Opticron Aurora BGA binocular. If you have any problems or
damage the instrument in any way please contact our Service Department.
