They focus the light and make distant objects appear brighter, clearer and magnified. This type of telescope is called a refracting telescope. Most refracting telescopes use two main lenses. The largest lens is called the objective lens, and the smaller lens used for viewing is called the eyepiece lens.

What image is formed in refracting telescope?

(b) Most simple refracting telescopes have two convex lenses. The objective forms a real, inverted image at (or just within) the focal plane of the eyepiece. This image serves as the object for the eyepiece. The eyepiece forms a virtual, inverted image that is magnified.

What is new about refracting telescope?

Refracting telescopes

Lenses are curved pieces of glass or plastic, which bend rays of light and can make objects appear bigger. Refracting telescopes use one or more lenses to collect and focus the light from objects in space, forming an image. Then, an eyepiece lens enlarges, or magnifies, the image of the object.
