Telescopic Binoculars — All thanks to the man who first invented the first telescope. Unfortunately he died anonymous. As they say, the Great live and die in silence. But Hans Lippershey who popularized the use of it was luckier to be recognized. Later on its use was extended to the skies by Galileo Galilee in the study of astronomy. With his first astronomical telescope he introduced the heavens to the world. Being the first of its kind, it had its limitations.
The arrangement of the glass lenses hindered further magnification. This was in the year 1609. Almost 100 years later another great scientist Sir Isaac Newton altered the telescope inserting a curved mirror that would absorb the light and reflect it to a particular point of focus which magnified objects millions of times greater than the ordinary lens. The telescopes that you and I use today follow the same designs but with larger mirrors and improved technology.
The telescope as the word suggests is an instrument facilitating the extension of a scope to a far distance. And the binocular is an extension of the telescope in usage. Telescopes collect more light and provide high resolution images allowing greater details to be seen of greater distances. They come with different eyepieces for different focal lengths and are hence very flexible in configuration. But the monocular design, heavier weight and high costs makes it necessary to look at a more comfortable replacement.
Binoculars, unlike telescopes are fitted with two objective lenses and prisms, one for each eye, making them more comfortable to use and cheaper due to its low weight and size. But the power of the telescope does not come with the binocular.
Looking at the negatives of both these instruments, some optics geniuses thought of combining their positives and landing at a fresh combo which would be called the telescope binocular. This would be the best of both with the powerful lenses of the telescope and the very comfortable design of the traditional binocular.
Some models even come with interchangeable lenses making different fields of view available. So the built-in lens of the binocular is done away with. If any of you out there is a budding astronomer, then you can be sure you have your best bet here. To see a great discussion about these instruments, look here astronomy binoculars.
Telescope binoculars are especially for the purpose of astronomy. They can however be used for other activities like bird watching or any such activity. Tailor made for the discovery of the skies; they are bulkier than the friendly binoculars and must be handled with care. But with no setup time, and easy portability, to the astronomer this combo pack has been a boon.
The high power astronomy telescope binoculars for amateur astronomers should not be confused with the the Large Binocular Telescope (LBT), which has been atop Mt. Graham in Arizona, USA, the result of over two decades of effort, and is the largest telescope to have ever been made in terms of light collection capacity. Its resolution has been unrivalled by any other optical telescope so far. Not even the very sophisticated Hubble Space Telescope.
Ever wondered how the first stars and galaxies formed or what the world beyond our solar system really looks like? Then you might get some clues to your curiosity from the LBT. It is one of the most remarkable advances in the quest to know the unknown. But why is it called a Binocular Telescope? That’s the topic of another article.
While it is true that almost any pair of binoculars will be better than the naked eye for viewing the sky, not all of them are created equal. It’s worthwhile to do some research to learn what makes a good pair of binoculars for astronomy before you invest any significant money.
There are so many different options available, with a million different combinations of features, stats, and materials. Let’s look at some of the most important specifications and identify the items you actually need to pay attention to in order to get the most out of your stargazing.
First you need to consider the power, which is how much the lenses will magnify whatever image you are observing. For instance, if a particular pair says that it is 8 x 50, it means that the images you see will be 8 times the size they would be if you looked at them directly with your eye.
While a higher magnification will certainly make objects in the sky larger, they do carry some disadvantages.For instance, you will see a smaller area of the sky, making it more difficult to figure out exactly where you are looking or to find a particular star.
It also makes it harder to hold the binoculars steady enough to get a good view of your subject. A magnification of 8 is a good target when you’re starting out, and it’s probably best if you stay under 10.
Objective lens size is the next important aspect to consider. The bigger the lenses that let in light, the brighter the stars will look. Bigger lenses (the second number in a typical binocular designation) will pull in more light and allow you to see more objects in the sky. In addition, it will make enjoying each heavenly body easier since you won’t be straining as much to make out faint glimmers.
Those two being the most important aspects for astronomy, you’ll find that there are many other options for you to choose from. How does the focus work, is there any kind of stabilization, what is the weight, size, and shape of the binoculars (partially driven by the objective lens size, of course), price, style, color, and the list just keeps going. Most of these come down to personal preference, and shouldn’t have too much impact on the quality of your viewing.
I’ve been in the optics industry for a while now and have interacted with a good many clients who love gazing at the stars and moon at night. But they come to me, saying, ‘I just want to appreciate the stars, and not have to fuss about setting up a telescope or figuring out how to polar align, locate objects’.
So I tell them, in all honesty, there is really no wrong in that, and a simple solution might just be – binoculars! A pair of astronomy binoculars is a great way to save money, save space and is a great gear to pick up, put in the back of the trunk when you go camping. At night, when the sky is really dark, star-gazing with binoculars lets you view the stars a closer and fall in love with dark sky sites.
For the less technical, binoculars also eliminates the need to polar aligned your telescope or having to purchase filters and eyepieces for. They are also usually adaptable on a tripod and you probably want to get one with Astronomy Binoculars. I will explain a little bit more further down this article. For now, let’s get to some basics.
The two important features you need to get comfortable with on Binoculars is their magnification and aperture. These are usually identified by the two numbers used to name the product. For example, the product named Saxon 25×100 Astronomy Binoculars features a magnification of 25 times, and an aperture of 100mm. The two numbers you always see in the product name of a binoculars almost always refers to magnification and aperture. Aperture also refers to the diameter of the lens (in millimetres).
For celestial viewing you need binoculars with a big aperture. The bigger the aperture, the more light is transmitted through the tube. You will notice most binoculars have an aperture ranging between 25 to 50mm. These binoculars usually fit easily into your hands and are great for general viewing.
Astronomy binoculars, however, tend to be double or triple the size of normal binoculars because large aperture is required in such low light conditions to transmit more light. Look for something around the range of 80mm or 100mm in aperture, and you’ll be fine.
Since these binoculars are going to be quite large and heavy (between 1.5 to 3kg), we recommend getting a pair that can sit on a tripod. Sometimes a tripod adapter needs to be purchase and other times it comes with it. It really depends on the brand and model you purchase.
Because these binoculars are so heavy, get a tripod so that you can view with your hands free. A pair of binoculars fixed on a tripod also means your views are almost free of hand shake. Image trying to hold up a 2kg pair for a few hours – you are going to tire out eventually!
I hope these articles help you understand the most basic points about viewing the stars with Binoculars. Happy Stargazing!
Premium telescope binoculars are handy tools for the aspiring astronomers. Telescope binocular viewing enables a person to oh-so-easily see heavenly bodies in space like stars and planets, asteroids, meteors and a host of other things that you cannot think of seeing with your naked eyes.
Telescope binoculars come with a variety of viewing ranges. Some of them have a very long range while others offer a more limited range. A 100 mm lens with 25x magnification will show you rocks on the moon and several other details.
On the other hand those with 40x magnifying capability can show you things even beyond like the moons of Jupiter and the rings around Saturn. However the ones with greater magnifying property may lack in clarity in their image, and they certainly require a tripod to steady them.
Telescope binoculars are essential in the study of astronomy. In order to make students of astronomy as well as the astronomers aware of the availability of wide range of these binoculars, there are a number of websites dedicated to Binocular Astronomy. Those of you interested in the subject can choose from the products that are displayed on them. They are displayed with all their features and properties.
Astronomy is an interesting subject and it is accentuated by these large astronomy binoculars. The vision that they give of the other planets add a new dimension to the study of astronomy. Telescope binoculars can be used to in the night to gaze starts in the clear skies. Minor details on the moon can be witnessed during the night. You can also photograph the sun during the day.
Telescope binocular view is slowly becoming very popular and many people have started gazing at the sky with them. Many schools also encourage their students to take up star gazing as their hobby. Telescope binoculars are becoming synonymous with astronomy.
Telescope binocular viewing is being improved every day. Now when you look at the moon, it looks so close to you that you can see the surface of the moon very clearly. The four largest moons of Jupiter were discovered and spots on the sun were noticed using telescopes.
Telescope binoculars are a boon to those who want to know more about the solar system. The study of astronomy is made interesting and approachable with this equipment.
It is not terribly expensive. Good quality astronomy binoculars may be purchased for under $200. They will give you all you need to cast your eyes heavenward – and be rewarded.
