Binoculars are wonderful pieces of equipment that can enhance many of our daily
activities including, birding, action sports, hunting, and even astronomy.
Essentially binoculars take a distant image, enlarge it through the use of
lenses for viewing, all while remaining small and light enough to be mobile. |
The actual makeup of most binoculars is fairly straightforward and simple. You
have the lenses at the end of the barrel called the objective lens that gathers
the light from the distant image and focuses it on the lens closest to your eyes
for viewing. Binoculars are really two small telescopes put side by side so that
you can view the desired image with both eyes instead of just one. This imparts
some measure of depth of field, much more so than with a single scope.
When selecting a pair of binoculars you will immediately find that two numbers
are used to describe their capability. These numbers are often expressed as "6 X
30" or something similar. Let's break the code so you will know what these
numbers mean.
The first number refers to the magnification power of the binoculars, or in
other words how many times the image is magnified. So if the number is 6, that
means that the image that you view through the lens is magnified 6 times it's
normal size.
The second number has to do with the size of the objective lens at the end of
the binoculars. It's good to know this number because the larger the diameter of
the objective lens, usually the more light will be let in for viewing the
distant image.
Now, let's put this information in use in the real world. You may think that
it's best to just get the highest magnification that you can get for binoculars,
but this is not true. At some point, hand holding the binoculars will affect the
clarity of a highly magnified image and the resulting shake will render the
magnification benefits useless. Generally speaking, anything above ten times
magnification should be mounted on a tripod instead of handheld. So if you are
planning to use binoculars for activities that do not allow you to be able to
bring along a sturdy tripod, you probably want to stay with a pair of binoculars
with 4 -7 times magnification.
As far as light gathering properties are concerned, if you plan on using your
binoculars in any kind of low light situation whether indoors, or at times of
day when there is low available light outdoors, then you need to have a large
objective lens, usually 30 or above, to make as much use of available light as
possible.
Finally, consider the weight of the binoculars before buying them. If weight
will be a consideration for activities such as hiking, then perhaps plastic
lenses will be best that are specially coated to produce a high quality, sharp
image. These can be more costly than glass lenses, but they are considerably
lighter. Glass lenses usually make for much better optics and clearer images at
a lower overall cost, but they can also be more fragile.
Generally speaking, more expensive pairs of binoculars have more attention paid
to fit and finish and will stand up to more vigorous use, but if you only plan
to occasionally use your binoculars, then a less expensive pair will no doubt
work fine. Also, remember that after the purchase
you should be sure to protect your investment with a suitable binoculars case.

Anyone Can Hand Feed Their Own Backyard Birds
This new video will guide you step-by-step through the quick, easy
technique that will open up a whole new world
of fun and excitement..... that the
whole family can enjoy.
You
will be having more fun than you could ever
imagine.....and
you won't
even have to leave your own backyard !
The very first time I sat in my backyard to try
this new
technique......in a matter of minutes, I had Blue Jays swooping
across the yard to take peanuts out of my hand!
Then as other birds such as
Chickadees, Red-breasted Nuthatches, White-breasted Nuthatches and
Downy Woodpeckers started using the feeder, just as with the Blue
Jays, in only a matter of minutes.....I was
hand-feeding them as well.
