Here's how it works:

* Objective lens: This is the large lens at the front of the telescope. It gathers light from distant objects and focuses it to a point.

* Eyepiece lens: This is the smaller lens you look through. It magnifies the image created by the objective lens, making it appear larger.

Refracting telescopes are known for their:

* Sharp images: They produce clear, detailed images.

* Ease of maintenance: Unlike reflecting telescopes, they don't require frequent adjustments or cleaning.

However, they also have some drawbacks:

* Chromatic aberration: This is a distortion of color at the edges of the image, caused by different wavelengths of light being refracted at different angles.

* Large and heavy: Large refracting telescopes can be very heavy and difficult to move.
