It is essential to understand that as magnification goes up, telescope image quality goes down and that it goes down much quicker in a small telescope. Few astronomical objects require more than 350x magnification and most observing is done at less than 200x, even with a large telescope. You probably don’t need as much as you think. It's a great telescope accessory to get started in stargazing. It also provides interesting facts and information about astronomical phenomena. A great tool for the beginner is a finderscope, a piece of equipment that will help you find various objects in the cosmos. It will help you locate the most common things to look at in the sky. If you are buying a telescope for a new astronomer, especially a child, it also makes sense to start with a telescope that is suitable to their size, age, and interest. When a telescope becomes a chore to move and set up because of its size, it’s doomed to collect dust in the closet. Even if observing will be done at home in the backyard, portability is still a factor. Many astronomers choose smaller telescopes because they need to transport them to locations where the sky is darker and more stars are visible. Large telescopes do translate into more objects seen and better images, but they are also more expensive and also less portable. When it comes to telescope sizes, not always. Optical quality and special features may allow a small telescope to outperform a larger telescope for some types of observing. However, this is a very general way to look at a telescope. A medium telescope generally means a telescope of five to eight inches and a large telescope usually means anything over ten inches in size. In addition, at 120x, the 10-inch telescope will produce images that are brighter and sharper than the 3-inch telescope.įor amateur astronomers, a small telescope generally refers to a telescope of 4 inches or less. For example, at 120x, a ten-inch telescope will reveal hundreds of objects not visible in a three-inch telescope. The larger the telescope lens or telescope mirror, the fainter the objects a telescope will reveal (the more objects that will be visible), and the greater the telescope magnification it can use and still produce a good image. This is usually part of the telescope's model description. Therefore, the size of the lens or mirror (the heart of the telescope) is used as a general way to measure telescope potential. Since any telescope, even a small one, can produce any given magnification with the right telescope eyepiece, magnification is not a useful way to rate a telescope. We'll tell you all about the best telescope to buy when choosing between reflecting telescopes, refracting telescopes, Schmidt-Newtonian telescopes, Schmidt Cassegrain telescopes, Dobsonian telescopes, and the Maksutov-Cassegrain telescopes. Learn how telescopes work with OpticsPlanet and become an avid astronomer for life. We have also included some telescope recommendations for beginning astronomers to make shopping easier. Here are some frequently asked questions about telescopes for the person buying gifts for an astronomer. So how do you choose a telescope for a new astronomer? With so many telescope models designed for the beginner, it is sometimes hard to figure out how to pick a telescope, especially if you are not an astronomer yourself. Astronomy is truly an interest that can last a lifetime, especially if you know how to pick a telescope that will continue to be used as the hobbyist picks up more skills. With a medium or large telescope, amateur astronomers rarely see everything there is to see with a telescope, even after years of observing. Even a majority of the smallest inexpensive telescopes are capable of revealing the rings of Saturn, the cloud belts of Jupiter, hundreds of star clusters, and even distant galaxies. A telescope makes a wonderful gift for someone who has an interest in the night sky. In this guide you’ll learn how to choose a telescope, including how to choose a telescope for stargazing and some tips on how to choose a telescope for a child.
