Prism Binoculars

Telescope binoculars are getting very popular these days as more and more people are going for it. Many people ask me if there is any difference between telescope binoculars and binoculars. The difference between the two is in its usage. Binoculars are used to get a magnified view of objects that are relatively close whereas telescope binoculars are used for viewing very distant objects - mainly for stargazing.

Telescope binoculars have the best of both binoculars and telescopes:

• You can view it using both your eyes, which means that your eye muscles will not get stressed.

• Sturdy and portable. You can carry it with you where ever you go.

• It has more focal length which helps you in stargazing.

• Focusing is very easy on telescope binoculars.

• Easily be mounted on a tripod for steady viewing.

• No set up time - just pull them out and start gazing!

There are many different types of telescope binoculars available on the market. There are a few things that you need to keep in mind while buying them:

First thing that you need to look for, while purchasing telescope binoculars, is 'porro prism' which are best for viewing in dim lights and make stargazing easy and enjoyable.

It is important to make sure that big astronomy binoculars have a provision for mounting on a stand. Mounting your binoculars using tripod or any fixed object will facilitate better viewing. Even a small shaking movement can disturb your view, from your focal point and moreover it is hard to keep the binoculars pointed in the same direction.

If you are interested in astronomy and do not use binoculars for watching the stars then you definitely are missing out on a great experience. It is such fun to watch stars in the clear sky with your telescope binoculars which are very easy to use. You can see different stars, constellations, moon and planets without straining the muscles of your eyes as the equipment facilitates viewing with both the eyes. The best thing about most of the binoculars is that they can be mounted very easily. They are pretty sturdy unlike telescopes which are very delicate and have to be handled very carefully. It does not take a long time for you to set it up on a tripod or any other stand. So just put the binoculars and tripod in a bag on your back - and get going!

You can always visit the website www.telescopebinoculars.com and get acquainted with different models of telescopes available with their prices. Buying online has become very easy and they sell directly from the manufacturer.

The next time you decide to go stargazing with your friends in the night make sure you carry your portable telescope binoculars with you and surprise everybody with its clarity and convenience.

What do the numbers mean in Binocular descriptions?

I am going to South Affica later in the year and plan on doing at least one safari.
I would like a really good pair of Binoculars but don't understand the numbers. i.e:
10 x 42 Roof Prism Binoculars
8 x 21 Binoculars
LX 8 x 42 Binoculars

can some-one help and possibly recommed a good pair

The first number is the magnification. The second number is the diameter of the objective lens in millimeters. So 10 x 42 means the binoculars would magnify the image to make it appear 10 times closer and the objective lens is 42 millimeters in diameter. The most popular binoculars are 8 power because the image remains fairly steady and they tend to have a wide field of view (how much you can see in the binoculars). 10 power are more difficult to hold steady. The image has a tendency to giggle because of hand motion. There is another number that is important but is not published so prominently. That is eye relief. It is the distance from the eye piece that your eye can be and still see the complete field of view. 18 mm is considered excellent. If you wear glasses at least 16 mm is necessary. Roof prism binoculars have become very popular these last 10 years. The tend to be fog proof and water proof. They are also more compact. The larger objective lens lets more light in and results in a brighter image. That is not too important except at twilight. A wider field of view allows one to acquire the target much easier because one can see more.

I do not know how much you wish to spend on a pair. For a one trip affair I guess I would not recommend spending a whole lot.

Here are some decent pairs that should serve you well.

http://www.eagleoptics.com/binoculars/bushnell/bushnell-h20-8x42-roof-prism-binocular

These are reasonably priced. They have decent eye relief of 17 mm and a decent field of view although not the best. They are fog proof and water proof.

http://www.eagleoptics.com/binoculars/eagle-optics/eagle-optics-denali-8x42-roof-prism-binocular

This pair is about twice as expensive. The field of view is considerably greater

http://www.eagleoptics.com/binoculars/vortex/vortex-hurricane-8x28-binocular

This pair is more compact with a 28 mm objective lens instead of the 40 mm. Also lighter.

You could spend much more on a pair, but unless you are an avid birder it is probably better to save your cash to buy beer.
