How do refracting telescopes work?
Answer»
Most refracting telescopes are made with two or more lenses.
The two lenses are called objective lens and an eyepiece lens.
The objective lens should be large so that maximum light can be collected from the source.
Using the light collected, the eyepiece lens which is small in size, produces a large image of the source.
