From the Greek tele – means far away, skopeuw – skopeo means to observe.
A telescope is understood to be a device that is used to observe space objects. Its function is to collect signals that come from distant radiation sources. But at the same time, the amount of energy that was collected in this case, the greater the area of the lens (see Telescope, lens). An example is a telescope with a lens having a diameter of one meter. It can collect about 30,000 times more light than the human eye (see Radiation receiver, eye). And a telescope with a mirror with a diameter of 6 meters is able to capture a luminous flux a million times larger than the human eye. In addition, the telescope has the ability to increase the size of distant objects.
