Telescpoes act as windows to the universe . It is with the help of telescpone that the study the solar syster and the view  conjunction of stars .Not just that,  the various planets , galaxies satellitres and asteroids that we get to see only in a books and magazines are more familiar to use via the telescpone . They act as barrier  breaking instruments between the human being and the outer space .the universe is not more a mystery to do exists beyond our reach and we owe it all to the telescpoes.

Filters these are very essential for telescopnes user because that the reduce the glare on the eyepiece and the scatter the light that be make it less strenous for us to views to object .

If we  are careful about remembering the above point then it wont take use long to choose a telescpoes the next time we want to buy for ourselves.

Eyepiece this is a very important piece of equipment and it absence can be render a telescope useless. Eyepiece come in a variety to the size and if you add more than one eyepiece to your telescope that you can the pleasure of viewing even that the tiniest and the distant object with the clarity.

Mounts are the stands for the telescope. It is a mount on which the telescopes rests. since to the telescope function in a favorbly in vibration therefore you should ensure that it is placed on a stable mounts.

Berlow lens a barlow lens help in the magnification of telescope . These lenses are available in different sizes and we must careful in choosing the size the best fits of eyepiece .

Though both the refractors as well as the refractor telescope are easily available in the market we should take the following point into consideration  before buying a telescope .

Do not get impressed by the magnification of the telescope.this is magnification alone is of no use if it just produces large but hazy images.

Resolution this enables the telescope to produce a more detailed image . So always not for a telescope, which has a higher solution . moreover since resolution is also determined by the aperture , there fore the larger the aperture the better the resolution .

Focal length the distance between the optical center of the eyepiece is known as the focal length . The focal length is what determines the magnification in telescopes.  Larger focal lengths imply more than magnification.
