Working of telescopes
Telescopes are used to get a closer view of the remote objects. They are used to focus the light from the objects to a point and
later magnify the image to form a better view.
This helps to view the astronomical objects which are not seen with the help of the naked human eyes. The view will be focused with the help
of the electromagnetic rays and thus can help to get the brighter images. There are different types of telescopes.
The telescope classifications essentially vary in the construction and the working. When the working varies, the purpose for which
it is used also varied greatly.
Though the basic use is to view objects at a distance, the area of application can vary greatly. To understand all these aspects
of the telescopes, it will be better to know more about the working of the telescopes in detail.
Before understanding the working of the telescopes, it will be better if you know where the telescope is defeating the human eye.
It is because here is no sufficient space in the retina that, human eyes can’t view the distant objects.
Here the telescope is trying to get rid of this difficulty with the human eye. There the eyes are given more area for viewing the
distant objects.
Telescope concentrates on the aspect that how to give more space inside the retina for
the images. This can rectify the problem that the distant objects are not close to the human eyes and so not clear also.
This is made possible with the help of the lenses that form a major part of the
telescope.
The working of the telescope is made possible with the help of the two lenses that come with them. They are known as objective lens and
eyepiece lens.
The objective lens is used to focus the light from the remote objects to a fixed focus point. The eyepiece lens is used to spread
the light from the objective lens to fall in a larger area in the eyes. Thus retina will get more area of the image at a distance. This is
not possible in the case of the normal eyes.
Thus the telescope will collect the light from the object to the focus point. Then it is spread it to a large area in the retina.
The light absorption is a feature of the diameter of the lens.
That is the aperture affects the ability of the telescope to concentrate the light in a better way. Thus this directly
proportional relation of the aperture and the brightness of the image will influence the efficiency of the telescope.
The best combination of the lenses can affect the superior magnification power of the telescope. Different eyepieces can cause
different magnification ability.
Aperture is difficult to attain as compared to the magnification. This is because better magnification can be obtained with the
help of the eyepieces where as it is difficult to get the aperture suitably arranged.
The working of the telescope is easy to understand. It is the variations in the combination of the lenses that differentiates the
telescopes in general from one another.
There can be a wide variety of telescopes, but the basic functioning is the same with the two lenses blending together to form an
effective combination of the lenses thereby giving better image view to the users.
