The ABCs of Binoculars

Binoculars are actually two telescopes placed side by side
so a viewer can see through them with both eyes. Unlike
monoculars which is one small telescope and can only been
seen through using one eye. The advantages of using
binoculars over monoculars are:
1. Binoculars are more comfortable to look through and
capture images better.
2. Binoculars give one a three dimensional image and
bring two slightly different images into one focus and
allows distances to be estimated.
3. They are easy to take with you and easier to keep
steady when looking through.
The most common form of binoculars are the hand-held
variety, which are extremely portable. Larger binoculars
can be uncomfortable and difficult to hold steady. Much of
the time, they must be mounted on tripods or other
supports.
Most binoculars are used to view objects at very far
distances and have to be focused for the viewer to see
things clearly. Focus adjustments on each set of binoculars
are different, some binocular lenses can be focused
independently while others can be focused at the same time
by turning a little wheel in between the telescopes. Many
viewers using prescription glasses do not need them to see
through most telescopes and can see more comfortably by
taking off their glasses.
Binoculars make distant objects look bigger. Numbers
describe the power of binoculars. The first number notes
the magnification power. The second number provides the
diameter of the objective lens in millimeters, which is the
measure of the binoculars' light-gathering power. For
example, a 7 x 50 pair of binoculars can magnify things up
to seven times and features a 50mm objective lens.
Viewers can use a pair of binoculars for bird watching,
star gazing, observing far off animals, spotting ships at
sea, watching a concert, or enjoying a sports game from a
"nosebleed seat." They can be used while hiking, camping,
boating and hunting. One fascinating use of binoculars is
looking at the night sky. They enable the user to spot far
more stars, comets, galaxies, and nebulae far better than
with the naked eye. For example, galactic clouds and star
clusters look dim when viewed by the naked eye, but with
binoculars they are much clearer. Unlike the inverted view
a telescope provides, binoculars show the world right-side
up, just as a person would see things normally.
Furthermore, binoculars with a wide field of view allow a
user to observe a wide area, making it easier to observe
star clusters, comets, and galactic clouds. Binoculars are
easy to operate and allow viewers to concentrate fully on
looking up into the sky.
