Binocular Basics--What to Look for and Why
One of the main ways to classify a binocular is by using a combination of its magnification and its size. For example, you will see that the Discovery WP PC range includes an 8x42 model. The number 8 denotes the magnification and means an object appears to be 1/8th of its actual distance away. In other words, an object 40 feet away appears to be only 5 feet from you and another 200 metres in the distance appears just 25 metres away.
For general wildlife or sports watching, an 8x binocular makes the perfect choice. This level of magnification makes the binocular easier keep steady for extended periods of time but still takes you closer to your subject. But for those that want to get even closer, the Discovery WP PC range includes 10x magnification models.
The second number is the diameter in millimetres of the objective lens (the lens at the end of the binoculars furthest from your eyes). This is the lens through which light enters the binoculars. As a result, a larger objective lens will generally allow the image viewed through the binoculars to appear to be brighter. This means that the binoculars will be effective in lower light conditions such as at the start and end of the day or when there is heavy cloud cover.
However, a larger objective lens also means the binocular will be heavier so you need to decide which feature is more important--a larger objective lens to help extend your viewing days or a smaller, more compact and lightweight binocular.
For astronomy, you might want to consider either the 8x50 or 10x50 models--the larger 50mm objective lens collects even more light.
