Your Astronomy Now

For the newcomer to stargazing or indeed planet gazing, a good pair of binoculars are a major step up from scanning the skies with the unaided eye.

You will be able to develop your astronomical ability by looking at stars, viewing planets and locating constellations before going to the relative expense of purchasing a telescope.

There are many benefits to using binoculars for stargazing.

* The cost, good binoculars can be a lot less expensive than a telescope
* They are much easier to handle and use for a less experienced skywatcher. They are smaller, lighter and don’t require any setting up.
* Binoculars provide a much larger field of view than the vast majority of telescopes. This makes finding objects easier. This is one of the biggest challenges faced by the beginner.
* Locating constellations, and observing comets is much easier with binoculars, as you can scan a lot of the sky quickly.
* Binoculars have lots of other uses and so you will get value from your purchase.

As well as your binoculars you will also need an astronomy sky chart to help you find your way around the skies.

A red flashlight is also handy. This allows you to look at your charts or any books you may have with out ruining your night vision. If you can’t purchase a red torch, just cover a normal white light torch with red cellophane.

If you have developed your sky watching skills with your unaided eyes, you will find it a lot easier to pick things out using binoculars. Planet gazing will be within reach with binoculars too.

A visit to your local library will be very beneficial. Try to find a book that will show what a certain planet or object will look through binoculars.

Also remember that when going out on a clear night for a spot of sky watching that the temperature can soon drop. So always wrap up warm.

If you have decided to use a large pair of binoculars, you may find a tripod with a binocular mount a great help.

It isn’t much fun finding a planet or constellation and then having the views ruined by your trembling hands.

A notebook is another good thing to carry. You can the write down and make notes about the things you have seen.

As with all things, the internet is absolutely fantastic for finding information about astronomy, and a quick Google will yield enough results and reading material to feed your hungry brain for a long time.

But even if your interest in astronomy only runs to learning the names of the stars in the sky,
a nice, small and compact pair of binoculars make stargazing and planet viewing more interesting.

This particular type of binoculars is made to accommodate various viewing needs. As you purchase it and then use it, you will eventually realize that it’s a great decision for you to invest on something like vanguard binoculars.

One of the things which should be your concern when it comes to using binoculars is eye strain. Since you will be using it to view a rather distant subject, you have to make adjustments to ensure that you can clearly see what you hope to see. However, binoculars are not purely magical in the sense that you automatically see what you want to see without making the necessary adjustments. However, with the use of vanguard binoculars you can actually come close to that. It offers eye reliefs feature wherein a viewer can still see his focused object even if he places the binoculars a few millimeters even centimeters away from his eyes. In effect, he does not really have to endure enclosing his eyes right onto the binoculars.

Another tough thing which people can experience with binoculars is that both lenses can be off sometimes. Vanguard binoculars are made in such a precise and detailed manner that one can easily adjust the left and right lenses to fit the resulting focus. The one responsible for this is the diopter focus which can be easily adjusted right on the vanguard binoculars’ eyepiece. And speaking of focus, these binoculars also have a near focus feature. This allows the user to adjust the focus of the lens according to the shortest distance possible for viewing a subject.

If you take the vanguard binoculars outdoors, you can just relax although you have to cross rivers of see sites right smack beside some flowing waterfalls. This is because this type of binoculars are made waterproof as well as fog-proof so that lenses will not be easily affected by changes in climate or weather caused by humidity. This is important because once the lenses fog up or get tainted with water it will be very hard to clean them. Surely you won’t like to go to all the trouble of disassembling your binoculars just to regain the previous focus.

In addition, vanguard binoculars also offer its users with more comfort and ease in using via its eyecup features. Of course, it won’t always be that viewers will have 20/20 vision while using binoculars. Those who cannot see clearly without glasses may concern themselves about using a pair of binoculars while wearing their eyeglasses. In vanguard binoculars, eyecups can be easily folded down so that your eyeglasses can replace its space. For those who have clear vision without the aid of eyeglasses, they will be able to enjoy the comforts of using the eyecups provided by vanguard binoculars.

Think about it, binoculars are inexpensive, highly portable and require no complicated setting up procedure.

Binoculars allow excellent moon views, and great viewing of star fields, comets and even deep sky objects. They are especially useful for beginners as the right way up view makes it easy to navigate the skies. With a little practice you can pick out several of the planets and even the larger moons orbiting Jupiter. Clusters like Pleiades look great because the binoculars wide field of view lets you have more of the cluster in view at once.

So how to choose which ones? Binoculars have two specifications marked on the body of the binocular in the form of 7x 50, where the first number represents the magnification (in this case 7 times) and the second the aperture (50mm in this case). When it comes to selecting the right binoculars for astronomy, aperture is the most important feature to think about. The bigger the aperture the more light is captured so the brighter and clearer the image will be. For astronomy use you will need at least 40mm aperture and preferably larger.

You will need a magnification factor of at least 7, maybe up to 10 if you have a steady hand. Any higher than about 10 times magnification and you will need to mount them on a tripod as the hand shake effect makes it difficult to get a sharp image.

There are giant binoculars available with higher magnifications and apertures which are designed for astronomy use but you will certainly need a sturdy tripod or mount to use them. These can offer excellent viewing up to about 25 times magnification with 100mm apertures.

This brings us to another point, a specification known as the ‘exit pupil’. This specification refers to the diameter of the shaft of light that reaches your eye. You can easily calculate it by dividing the aperture by the magnification so that 7 x 50 binocular has an exit pupil of just over 7mm. Capturing as much of that as possible is good as it means all the available light is getting to where you want it, i.e.your eye. If you are still in your twenties you can probably use all of that 7mm exit pupil above as your pupils will dilate to about that size in very dark conditions, however as you get older your pupil does not dilate more than about 4 to 5 mm so large exit pupils are wasted.

You might notice another specification marked on the binocular, the field of vision (FOV), it refers to the apparent ‘width’ of your vision as you look through the binoculars. It will be expressed as an angle in degrees or a measure such as 340 feet at 1000 yards. For astronomy use we can generally ignore that factor, it really does not matter a great deal at the distances we’ll be viewing at.
