Two large objective lenses.
Large telescopes have improved resolution over small telescopes and as such can gather clearer images of objects further away.
Refracting telescopes suffer from chromatic aberration, refracting telescopes have several surfaces to shape and polish, making large glass lenses without interior defects is very difficult, and large glass lenses are more difficult to support than large mirrors.
Telescopes are not dangerous in normal operation. A large telescope might hurt you if it fell on you.
Not necessarily. Refracting telescopes can be large, but reflecting telescopes can also be quite large and often have larger apertures due to their design. The size of a telescope depends on its purpose and design specifications rather than whether it is refracting or reflecting.
Zhumell telescopes are made in China. Zhumell is an American brand that designs and sources their telescopes from manufacturers in China to offer quality products at affordable prices.

Sky-Watcher sells a large variety of telescopes. These telescopes range greatly in price and options. It is a good idea to investigate the various telescopes they offer, many are labeled perfect for beginners.
The discovery of additional planets was made possible by advancements in telescope technology, particularly the development of large ground-based telescopes and space telescopes like the Hubble Space Telescope. These telescopes allowed astronomers to observe distant planets more effectively and detect previously unknown planets orbiting other stars.
Scientists use telescopes, specifically large ground-based telescopes and space telescopes like the Hubble Space Telescope, to study Eris. These telescopes allow them to observe Eris' size, shape, surface features, and composition.
They are refracting telescopes(:Large refracting telescopes are no longer built because there were too many problems with them. There was color distortion, light pollution, and when the object hits the focal point it turns upside down. Then you don't see the object for what it really is, you see it upside down and weird-ed out. They are to complicated and scientists believed they should just stick with the simple, small, original refracting telescopes!!!!-Meghan Betts (8th grader)
It is cheaper and easier to create mirrors rather than lenses. Large lenses become difficult to support the larger they become. Additionally, mirrored telescopes fold light waves so that a telescope can be shorter, the same size telescopes with lenses are greater in length.
