It gathers the light coming from an object.
A refracting telescope is a type of telescope that uses a lens as its objective to form an image. This is different from other type of telescopes because it has a objective lens.
A refracting telescope is a type of optical telescope. It was used in astronomical telescopes and spy glasses. Objective lens are used to produce the image.

The "objective" lens (as opposed to the eyepiece).
The two lenses on a refracting telescope are typically called the objective lens (at the front of the telescope) and the eyepiece lens (at the back of the telescope). The objective lens gathers and focuses light from distant objects, while the eyepiece lens magnifies the focused image for the viewer.
Practically all telescopes which use lenses, normally the refracting type. the Reflector use objective Concave Mirrors, but even these need eyepieces or finder scopes.
The main optical element of a refracting telescope is the objective lens. This lens collects and focuses light from distant objects, forming an image that can be magnified and observed through an eyepiece.
The telescope you are referring to is likely a refracting telescope. In a refracting telescope, light enters through an objective lens which bends the light rays to a focal point where the image is formed. This type of telescope is commonly used in astronomy and for terrestrial viewing.
Yes, a telescope typically uses convex lenses to gather and focus light. The objective lens, which is usually convex, collects and refracts light to create an image that can be magnified by the eyepiece lens.
The largest refracting telescope in Wisconsin is located at the Yerkes Observatory in Williams Bay. Built in the 1890s, the Yerkes Observatory's 40-inch refracting telescope is one of the largest of its kind and was once the largest in the world.
The objective lens in a refracting telescope typically has a shorter focal length compared to the eyepiece lens. This is because a shorter focal length allows for higher magnification and better light gathering capabilities.
