When Two eyes are Better than One:


Lisa Wright argues that Astronomy Binoculars

make a Great Alternative to a telescope

     The telescope is always considered the most essential tool for any astronomer, whether he or she is an amateur or a professional. If you have decided to pursue your passion in astronomy, you may be wondering what one to buy. Sure enough, the best gadgets will offer you a crystal clear view of the heavens for your full enjoyment. But for any novice, the operation of these complex devices is relatively difficult and these are expensive to purchase. Given the various sizes and different zooming functions of telescopes, you are confused on which one should you acquire that gives you outstanding performance and good value for your money.


     The basic thing that you have to consider prior to acquiring one is to fully understand your needs in pursuing your stargazing objectives. While entry level and full-length telescopes can allow you to extremely distant objects in close-up view, these gadgets are relatively cumbersome to carry. You need to look for an alternative which is portable and easy to set up.


     A pair of astronomy binoculars is highly recommended for starters. Those used for stargazing are similar to the ones that we typically use for bird watching or seeing your favorite football game from the stands. The only difference is that the ones for astronomy are fully equipped and optimised for that purpose. There are four advantages that astronomy binoculars can offer you...


- They are less expensive compared with full-length telescopes. For novices, the price of telescopes is the biggest issue. You may feel pressured to keep up with your buddies in astronomy clubs who have the most advanced ones. However, you should not overlook the fact that there are other things to consider aside from buying a telescope. You may need to buy accessories that will enable your device to function properly. There may be research materials and books that you need to acquire. Fortunately, a pair of astronomy binoculars can allow you to stretch your budget.


- There are fewer accessories. Full-length telescopes are designed for serious sky-watching. Hence, they are equipped with many adjusting knobs. You need to fully orient yourself on how to set it up so that it will be able to provide you the best views of the night sky. Constantly tweaking the device may be inconvenient for beginners.


- They are easy to operate and maintain. All telescopes require regular maintenance to keep them at an optimum level of performance. However, the more sophisticated ones need even more complex servicing. Failure to conduct these procedures can result to faster wear and tear of these devices. The good news is that astronomy binoculars require less maintenance.


- They are portable and versatile. There are times when you need to go to other places to get fantastic views of the sky. Your astronomy binoculars are the best one to bring because it is lightweight compared to other telescope kits.


Astronomy binoculars have a similar structure to typical binoculars. They are actually a pair of telescopes that are fused together consisting of two sets of lens. When looking through the binoculars, the ones called ocular lenses are the closest to the eyepiece. On the far end of the device are called objective lenses. When choosing a pair of binoculars, take note of the magnification ratio that is indicated outside the unit. This consists of two numbers that indicate its visual range. The first number represents the magnification power of the ocular lens and the second is the capacity of the objective lens. For example, one that has a rating of 15-40 means that the ocular lenses magnify vision 15 times the actual size and the objective lenses capture 40% of the image seen by your naked eye. Simply put, the bigger the first number, the greater distance that your binocular can reach. And the bigger the second number, the greater is the visual field.

The issue that matters in choosing a binocular is to determine your needs. If you want to have a wider view of the night sky, a low-powered binocular is recommended. You can choose a high-powered one if you prefer highly magnified images. If you want both advantages, look for one that is well-balanced on its zooming power and visual field in order for you to enjoy watching the night sky for hours.
