Planet Science Magazine - Make your own telescope

A few days, and the month of Ramadan will be resolved by its great spirituality.To determine the surprise of the holy month and the date of the beginning of fasting, the observatory use telescopes to monitor the crescent of the Arab month.And to be able to monitor the crescent of Ramadan yourself, we came to you in a simple way that you can follow its steps to make your own telescope.

Telescopes and their different types

Telescopes are used to monitor celestial bodies by collecting light from these bodies and focusing to form a close image of them.The Italian scientist Galileo Galile.

هناك أنواع متعددة من التلسكوبات، تختلف وفقًا لنوع العدسة الشيئية⁽¹⁾ التي تؤدي مهمة تجميع الضوء.If the new lens is glass and plSed at the front of the telescope, it causes the refrStion of light through it, and the telescope is of the type..In the lazy telescope, light gathers at the focal level, while the in -kind lens is plSed behind the focal level so that the observer can see the heavenly bodies. قد يحتاج الأمر إلى إضافة عدسات أخرى لتقليل الزيغ اللوني⁽²⁾ وتشتت الضوء الناتج عن اختلاف الأطوال الموجية للأشعة الضوئية.

And if the object lens is a glass mirror plSed at the end of the telescope, it causes the reflection of light, and here the telescope is of a reflective type, and is also known as the Newton telescope.In this type, the object is usually concave, and because it reflects the light, the image turns at the focal level.

There is also a Casagerin Schmidt telescope, which is charSterized by its small size.It depends on a series of mirrors to fold the path of light, and a basic spherical mirror to concentrate the parallel rays of light on a convex secondary mirror.Then this light reflects again through a hole in the basic mirror to the lens.

Now, it's time to get to know together the steps to make your own telescope.Before you start, there are some terms that must be recognized first:

Required tools

Steps

Terminology

(1) The objective lens is those close to the object to be rounded, unlike the in -kind lens that is close to the eye of the observer (2) The color aberration indicates the deformation of the image as a result of the different refrStion coefficient lenses and the difference of light waves.
