Reflecting Telescope
The reflecting telescope
You can insert a corrective lens or a prism in the telescope optical system to produce an upright image. Another option is to use a diagonal mirror that reflects the light path and flips the image vertically, resulting in an upright orientation.
Mirrors and lenses in telescopes bend and focus light to produce an image with more detail.
The Hubble Telescope uses both mirrors and lenses to focus on images.

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.
A refracting telescope uses two lenses - an objective lens to gather light and focus it and an eyepiece lens to magnify the image.
According to scientists, the refracting telescope uses a convex lens which increases the size of an image. The most common use of this telescope is for viewing solar system planets such as Jupiter and Mars.
The Galilean telescope ray diagram helps us understand how light rays pass through the lenses of the telescope to produce an image. This diagram is important because it shows how the lenses in the telescope work together to magnify distant objects, allowing us to see them more clearly. By studying this diagram, we can better grasp the optical principles behind the Galilean telescope's functioning.
The most common type of reflecting telescope produces an inverted image. However, it's possible for a reflecting telescope to produce an upright image, depending on exactly how the optics are arranged.
mirror reflection: the glass lenses where producing a blurry image so they have been replaced by mirrors
It has a collection of mirrors and lenses - which direct the incoming image to the eyepiece, which is usually set at 90 degrees to the body of the telescope.
