Telescopes still have their place as an important instrument in science too. The best example of this is the Hubble Space Telescope, which has helped scientists understand space in much greater detail — the Hubble has a ton of data, and this one picture represents thousands of galaxies in a simple image.
One main use of telescopes for amateurs nowadays is to use them for astrophotography. Whilst a telescope alone can give us a good view of the sky, if you use them with a good camera — DLSR or CCD — then these kind of images can be reproduced.
Though they function in a similar way to one another they both use lenses , they really cannot be compared with each other as they are design with different goals in mind.
Whilst a microscope can be used for seeing a close object in extremely close detail, a telescope can be used for seeing distant objects in good detail too. Differences between microscopes and telescopes A microscope uses artificial light, whereas a telescope relies on natural light — Part of the way that telescopes work is by utilizing and drawing in light to portray the image of the sky.
Equatorial mounts are designed for easy tracking as stars and planets move through the night sky. Some are equipped with a motorized clock drive that keeps a constant rotation matching with that of the Earth, allowing for long-exposure astrophotography. Eyeglasses are a simple example of a microscope, and the more widely known variety is properly called a compound microscope.
Since the mids, microscopes have been used to study anatomical structures that are invisible to the naked eye. More recently, microscopes have been adapted to use multiple varieties of non-visible spectrum energies to observe increasingly minute details of the natural world. Microscopes are commonly categorized by how they generate their images — via light, photons, electrons, or scanning probes.
The two most widely known types of microscopes include:. They use refractive glass to focus light onto the eye and have a practical maximum magnification power of x. Optical microscopes are the most widely available and often the most affordable instruments in this category. Electron microscopes focus a high energy beam of electrons on a sample, producing a composite image in combination with a magnetic lens.
Divided in transmission electron microscope TEM and scanning electron microscope SEM categories, they are capable of magnifying images up to 15 million times their original size.
The tool of choice for observing objects too small to be seen with the unaided eye, microscopes have found their way into scientific research in multiple disciplines. More powerful microscopes are seen in cutting-edge physics research, where scientists are studying the smallest known forms of matter for hints as to how life came to be and ultimately, the nature of reality itself.
By combining an objective lens near the specimen with an eyepiece on the opposite end, compound microscopes produce an enlarged image of the specimen in question. Focusing mechanisms change the position of the lenses, allowing for multiple levels of magnification in a single piece of equipment. Common optical microscopes may produce magnifications up to around x, while electron or scanning probe microscopes may magnify up to 1 million times or more.
As magnification increases, the focal length and therefore, available field of view decreases. The Benefits Of Online Shopping. Effect of Data Loss. Eliminating Home Theater Hum and Noise.

A microscope should be used when viewing small specimens.
This may include cellular organ structures, different types of germs, or bacteria samples. Microscopes are used in many scientific fields and they are easy for hobbyists to obtain as well. Both microscopes and telescopes use an objective lens. This gathers light from the actual object or scene that is being observed by the viewer. They also both specialize in magnification.
They will allow you to get a closer look at an object that is too difficult for your naked eye to see. It makes the image appear larger and more clear to your eyes. You can see the movement in cells under a microscope or the movement of shooting stars in the sky through a telescope. Both of these instruments are used to study and help us better develop knowledge on things that we do not have the natural ability to see.
They help us improve our faculties so that we better understand everything from the heavens above us to the cells all around us. Both tools help us better understand a previously unseen world.
