The most common alternative is the binoculars, which have been used for centuries and still remain popular today. There are many alternatives to telescopes. Somewhat fragile – if the lens get scratched, it will be slightly more difficult to view.It cannot be used for other purposes such as viewing documents or pictures, reading books and magazines, etc. Can only be used to view far sighted objects. However, if both scopes have different magnification, then they would appear very different sizes on screen, even though their actual size hasn’t changed at all! For example, you could have two scopes that both show Jupiter as being about half a degree across. Magnification PowerĪnother thing to consider is magnification power this determines how much bigger an object appears in your viewfinder than it does with just your eyes alone. A larger aperture means more light gets into the scope, which makes it easier to see faint objects like galaxies and nebulae (clouds of gas). The aperture, or how big the telescope’s lens is, will determine what you can see in your viewfinder and through your eyepiece. What to look for when comparing a telescope? Aperture CatadioptricĪ catadioptric telescope combines both lenses and mirrors in one telescope body this allows them to be smaller than either reflectors or refractors, but still gives good image quality with less chromatic aberration (color fringing). Reflector telescopes use mirrors instead of lenses and can be much larger than refractors because they don’t have to fit inside a tube like the lens does. It’s also an excellent tool for educators, scientists, or anyone else interested in studying our solar system and beyond! What are the types of telescopes? RefractorĪ refractor is a telescope that uses a lens to focus light onto an eyepiece that magnifies it for viewing. A telescope is a great way for beginners and experienced observers alike to enjoy astronomy. Telescopes help us learn more about what is out there in space around us – we have learned so much from telescopes over the years!Īnyone who wants to see more of the universe.A good telescope will allow you to view things like comets, asteroids and meteors up close as they pass by Earth or even land on our planet’s surface!.You can use it to look at planets, galaxies and other objects in space that are too far away for you to see without a telescope.It helps you see the stars better than with your naked eye.Telescopes can be used for many different purposes, including astronomy (observing stars), navigation (finding your way by looking at distant objects like mountains) and spying on people! Advantages and Applications What are the 5 benefits of a telescope? The simplest telescopes are just lenses, but more complex ones use mirrors to reflect light onto a lens or other mirror. Telescopes collect light from an object and focus it into the eye of the observer. The word “telescope” comes from Greek words meaning far-seeing or long-sighted, because telescopes make things look bigger than they really are. It does this by collecting light from the object and focusing it to form a magnified image of the object. A telescope is an instrument that makes distant objects appear closer.
