The lens L1 is placed at a distance 2f from the object, which forms an erect image. It creates large magnification, Superior resolving power per inch of aperture, Its field of view is wide, Superior performance in inferior conditions image steadier, The image is The working principle of the terrestrial telescope uses three lenses. At magnifications of 30x or lower, the benefits of these objective lenses are hardly noticeable when compared to conventional glass objectives. Now when the image is formed, it is a virtual, inverted, and highly magnified image of the object at infinity, The final image is formed at the infinity and then the telescope is considered to be in normal adjustment. Telescopes in space are able to operate twenty-four hours a day, free of both Earth's day-night cycle as well as clouds and other weather conditions that can hamper observing. Because of the protective effect of the atmosphere, ground-based telescopes cant pick up the lethal, invisible portions of the electromagnetic spectrum such as ultraviolet rays, x-rays and gamma rays. The working of telescopes is based on the principle that when an object that is to be magnified is placed at a large distance from the objective lens of an astronomical telescope, magnified, virtual, and inverted images are formed at the least distinct vision when held close to the eyepiece. The telescope requires a few lenses to focus on objects and an eyepiece to see a magnified image.
