Astronomy Binoculars – A Great Alternative
It seems from the moment you begin to take your love of
astronomy seriously, the thing that is on your mind is what kind of telescope
will you get. And there is no question,
investing in a good telescope can really enhance your enjoyment of your new
passion in astronomy. But don’t be too
hasty to keep up with the big wigs in the astronomy clubs that have advanced
telescopes. There is another alternative
that can give you most of the advantages of a telescope and some extra
flexibility and reduced cost to boot.
That alternative is a good pair of astronomy
binoculars. Mostly we think of
binoculars as the thing you use to see the football game when you have to sit
in the cheap seats. But if you do some
homework and had a good grasp on what your stargazing objectives are, the advantages
of astronomy binoculars over an entry level telescope can be pretty convincing.
*
As a rule, they are cheaper. So you can get a lot of good stargazing at
much less of an investment. You can
always spend more money later but for now, this may be just the solution for
you.
*
There are not so many accessories. To own and operate a telescope takes a lot of
orientation to how to set up and use the device. Beyond that, tuning it for optimum view and
diagnosing it when you have problems can sometimes make the telescope more of
the passion than stargazing itself.
*
It is much easier to use. If you have not bought a telescope yet, you
may have seen telescope owners going through a laborious set up and break down
discipline for each use. This is time
they are not looking at the stars. The
binocular users are happily stargazing as this goes on.
*
Binoculars are lightweight and portable. Unless you have the luxury to set up and
operate an observatory from your deck, you are probably going to travel to
perform your viewings. Binoculars go
with you much easier and they are more lightweight to carry to the country and
use while you are there than a cumbersome telescope set up kit.
So give the binocular option some consideration. To make the most effective choice, however,
here are a few facts about astronomy binoculars that will help you evaluate
which ones are best for you…
Binoculars have two lens sets, one at the end of the eyepiece
and a set right next to your eyes. The
ones closest to the eye are called the ocular lenses which magnify the image
(make it bigger). The ones closest to
the sky are called the objective lenses and the size of these lenses will determine
how much sky you can see at once. So
anytime you are evaluating binoculars, there are two numbers associated with
the set. So if the binoculars have a
rating of 15-40, that means that the ocular lenses magnify 15 times and the
later number is a relative number to how much of the sky you can see. The higher the second number, the more you
can see. The explanation is simple. The bigger the lens, the more light it lets
in. But be aware that the bigger the
second number, the larger, heavier and more cumbersome the binoculars will be.
You will have to balance these two numbers with both your
budget and what you want the binoculars to do for you. If you decide to go with a lower power
binoculars, you could become frustrated with what you can see and you may have
to take your eyes away from the view to get your orientation and consult the
star map more often because your range of vision is so limited.
There will also be a temptation to buy a set of binoculars
that have zoom functions and other features that will allow you to use it for
other purposes such as hunting, whale watching or seeing the football game from
the cheap seats. While this is good
economy, those functions will get in the way when you are using the binoculars
for astronomy. So if you are considering
this purchase as your alternative to buying a telescope, our advice is buy
binoculars made just for astronomy and don’t take them to the ball game.
