That telescope you are refering to is called a refracting telescope.
Cameras and reflecting telescopes gather light using mirrors and lenses.
Reflecting telescopes use mirrors to collect and focus light, while refracting telescopes use lenses. Reflecting telescopes typically have a closed tube design which protects the mirrors from dust and other contaminants, while refracting telescopes are more prone to chromatic aberration. Reflecting telescopes are generally easier to manufacture at larger sizes compared to refracting telescopes.
Two large objective lenses.
lenses
Good telescopes don't use glass lenses for magnification, because they refract different colors is slightly different angles (known as prism effect), but they use spherical mirrorsinstead. Telescopes with lenses have the advantage of being smaller, cheaper and lighter.Therefore refracting telescopes use lenses, and reflecting telescopes use mirrors.
Lenses and/or mirrors
They both have lenses.
Yes, they both use lenses.
Chromatic aberration can be a problem for astronomers using refracting telescopes and camera lenses, as it can cause color fringing and reduce the image quality by not focusing all colors to the same point. Reflecting telescopes, which use mirrors instead of lenses, do not have this issue.
I believe the name of the first telescope was called the "telescope." The word was created from the Greek tele = 'far' and skopein = 'to look or see'; teleskopos = 'far-seeing'.
Yes. Lenses are used for glasses (correction for eye problems), for microscopes, telescopes, and other applications.Yes.

Refracting telescopes suffer from chromatic aberration, refracting telescopes have several surfaces to shape and polish, making large glass lenses without interior defects is very difficult, and large glass lenses are more difficult to support than large mirrors.
