A telescope magnifies the image that we as humans can see through the use of a magnifying glass (eyepiece) in combination with a lens. The stars themselves are not so much bigger because of their distance, but the number of stars, the brightness and the structure becomes clearer with the use of a telescope. Due to the construction of a telescope, the diameter of the lens plays the main role when we talk about the sharpness of the image. With a larger diameter, the telescope captures more light and you can therefore observe fainter stars better. The first telescopes date back to 1608 and were designed in the Netherlands.
There are several telescopes on the market, each of which uses different techniques to enlarge the image. We've outlined three types.
The eyepiece is close to the point we look through with the eye. This part of the telescope consists of several lenses that make the image perfectly parallel again. By turning the focus knob, the eyepiece can move in or out, allowing us to focus the image. By changing the eyepiece, the magnification factor of the image can be changed. Too large a magnification can cause blurry images, but with a set of eyepieces , you can test different effects.
For observing celestial objects it is important that the telescope can be placed in a stable manner, so that no vibrations arise in the image. Many telescopes are heavy and can be provided with more stability using a tripod. The tripod is already included with some telescopes, but not in other cases. It is therefore advisable to purchase a Tripod .
With a telescope, you can view beautiful images of the universe. It can be annoying when there is a blur or a lot of dust on the lens. It is therefore important to store parts such as eyepieces in a dust-free case. A lens cloth, air pump or lens pen can offer a solution to the various options for keeping the lens clean.
