a refractor uses a lense, a reflector uses two mirrors, IS THAT SIMPLE ENOUGH?!
The largest visible light telescopes are now all ground-based, such as the Keck Observatory in Hawaii or the Very Large Telescope in Chile. These telescopes provide high-resolution images and data of celestial objects in visible light.
A refracting or refractor telescope is a dioptric telescope that uses a lens as its objective to form an image. The refracting telescope design was originally used in spy glasses and astronomical telescopes but is also used in other devices such as binoculars and long or telephoto camera lenses.There are two basic types of telescopes, refractors and reflectors. The part of the telescope that gathers the light, called the objective, determines the type of telescope. A refractor telescope uses a glass lens as its objective. The glass lens is at the front of the telescope and light is bent (refracted) as it passes through the lens. A reflectortelescope uses a mirror as its objective. The mirror is close to the rear of the telescope and light is bounced off (reflected) as it strikes the mirror
Most professional research telescopes are reflectors because reflective surfaces provide higher light-gathering capabilities, allowing for the collection of more light and producing brighter images. Reflectors are also easier to construct in larger sizes compared to refracting telescopes, which helps in observing fainter astronomical objects. Additionally, mirrors used in reflectors are less affected by chromatic aberration, improving the overall image quality.
Yes, professional astronomical telescopes typically have greater magnification capabilities compared to telescopes sold in stores. This allows astronomers to observe celestial objects with greater detail and clarity. Professional telescopes also have larger apertures and specialized optics to gather more light and enhance image quality.
Yes, there are telescopes aboard many satellites that perform astronomical observations.
Refractors (with lenses)Reflectors (with mirrors)
Professional telescopes often select reflectors over refractors as their primary optical design because reflectors are generally more cost-effective and can be made with larger apertures, allowing for better light-gathering capabilities and higher resolution images. Additionally, reflectors are less prone to chromatic aberration, which can distort images in refracting telescopes.
Most large telescopes are reflectors instead of refractors because reflectors are better at gathering and focusing light, allowing for clearer and more detailed images of distant objects in space. Reflectors also do not suffer from chromatic aberration, a common issue with refractors that can distort images.
Most large telescopes are reflectors because they can be made with larger apertures and are less affected by chromatic aberration compared to refractors. Reflectors also allow for easier mounting of additional instruments and have better light-gathering capabilities.
The reason people build larger Telescopes is because smaller telescopes have a smaller power to them, which results in less detail the farther they look. Larger telescopes use much larger lenses to see much farther and with much more clarity.
Many companies sell astronomical telescopes for purchasing. Companies that sell this product include Amazon, Orion Telescopes & Binoculars, and Young Explorers.
All telescopes work best in the vacuum of space. Aside from that, "where" really is not a great factor compared to other types of telescopes. The distinct advantage of some reflecting telescopes is that they don't suffer from chromatic aberration like refractors do.
Reflecting telescopes give a brighter, clearer image that refraactors in many cases. Add to that the fact that refractors become very impractical with objective lens sizes much above 40 inches, while reflectors can have mirrors of 200 inches and more.

Thousands of people still do build their own astronomical telescopes; it isn't that hard to do.
