How does a Galilean telescope differ from the simple telescope?

Similar to the astronomical telescope, what's the difference between Galilean telescope and astronomical telescope?

An astronomical telescope can be described as an optical instrument that magnifies distant heavenly bodies such as stars, planets, satellites, and galaxies. Galilean Telescope, also known as a terrestrial telescope, is an optical instrument that magnifies distant objects.

The same goes for telescopes. What type of lens are you using? These lenses focus light to magnify distant objects and make them appear brighter, clearer, and more vivid. This type of telescope can be called a refracting scope. Refracting telescopes usually use two main lens. The objective lens is the largest lens. The eyepiece lens is the smaller one used for viewing.

What is the Galilean telescope in this regard?

Galilean telescope is an instrument to view distant objects. It was named after Galileo Galilei (1564-1642), who was the first person to build one. He discovered Jupiter's four largest satellites: spots on the Sun and phases of Venus.

Are astronomers using reflecting telescopes or refracting?

Astronomers use telescopes for gathering light, resolving fine details, and magnifying the image. Refracting telescopes have a mirror to focus light. They are also less expensive than reflecting telescopes with the same diameter. Reflecting telescopes are also free from chromatic aberration.
