Telescopes For Stargazers
By Cedric B Georges
Before the invention of the telescope, mankind’s understanding
of the world was limited to what could be seen and was
near enough to study. Translated as "far seeing,"
telescopes provide a clear image of objects at great
distances from the viewer.
They have assisted many fields, from the study of the
stars and night skies, to improved navigation over land
and sea. Many of the items we use today, such as camera
lenses, binoculars, binocular spotting scopes and microscopes,
are all directly related to the telescope.
Telescopes Over Time In History
The earliest known telescope was created in 1608, and
Galileo Galilei built his in 1609. Galileo is credited
with the first astronomical uses of the telescope. Initially,
it was used to spot ships. Johannes Kepler further improved
upon Galileo’s design in 1611.
From its modest creation from a pair of lenses, the
telescope of today bears little resemblance to its ancient
ancestor. The telescope falls into three categories:
reflecting, refracting and catadioptric. A reflecting
telescope uses an arrangement of mirrors, a refracting
telescope uses an arrangement of lenses, while a catadioptric
telescope uses a combination of lenses and mirrors.
The First Practical Reflecting Telescope
Telescopic research is an area where technology has
advanced. When presented with the limitations of the
refracting telescope, development of the reflecting
telescope commenced. Initially designed in 1616, it
wasn’t until 1668 that Sir Isaac Newton developed the
first practical reflecting telescope.
If people want their telescopes to provide better images,
then they must have a larger primary reflector. Today’s
optical systems range from 11 meters down to less than
2 meters but there is a problem with all ground based
optical systems. Atmospheric distortion can hinder the
images seen from the ground, yet there is a solution:
put the optical systems into space, as has been done
with the Hubble Space Telescope.
Since its beginning in renaissance Venice, the telescope
has assisted or directly contributed to numerous advances
or discoveries. Ocean navigation depended upon it. Astronomy
was born from it.
Cameras Were Developed From Telescopes
Cameras were developed from it. Just to name a few.
And we haven’t finished learning yet. There is still
a lot left to learn about these miraculous inventions,
and mankind has, and will continue, to benefit immensely
from these discoveries.
Just think...it is amazing to take a look at the newest
technology for telescopes and not be in awe of the fact
that it all started with a couple of pieces of broken
glass. Mankind is continuously developing new optical
systems to correct and improve upon the problems of
existing systems.
Before long there will no limitation on ground based
systems that suffer from atmospheric distortion. There
will also be new orbital platforms that send back information
so that we can see the stars much clearer.

More Binoculars Facts....
There are many sports out there for you to become involved
with and to enjoy all year long. But you do not have
to be a sporting enthusiast with a weapon in order to
enjoy nature.
When springtime rolls around and the world begins to
turn green, you can get outside and check out the new
baby animals as they enter the world. But you want to
stay away from them because a mad mama is the last thing
you want chasing you through the woods. The solution
is a pair of binoculars to observe the animals from
a distance.
It is a time to enjoy the blossoming life and see all
that there is to see with the new born animals and older
animals venturing out. The best way to observe these
creatures is through the telescopic lenses of binoculars.
You can find a pair of these miraculous wonders in many
sporting good stores and online.
Any sporting enthusiast or bird watcher can attest
that there is one piece of equipment that is absolutely
essential and that is a binocular. Binoculars are optical
devices used to look at objects far away.
They are not as powerful as a telescope but they do
the job pretty effectively. They allow the sporting
and bird watching enthusiast to get an up close view
of animals without putting themselves or the animal
in danger.
