The image seen through monoculars appear in their correct orientation through the use of two prisms, whereas in most telescopes the images are inverted. Are you planning to buy night vision binoculars?
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. To correct this, two prisms are placed inside the binoculars, between the objective and the eyepiece. The soft or rubber fold-down eye cups will give eyeglass wearers a better view by allowing them to see the entire field.
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. They can withstand complete immersion in water and remain dry on the inside. The first number gives the power of the magnification and the second number tells the diameter of the objective lens in millimeters which measures its light gathering strength.
Choosing a telescope is not an easy choice to make and is one that really needs research. If you are only going to spend a couple of hundred dollars for binoculars don't even bother to look at the higher priced pairs. Higher quality glass also yields brighter images and sharpness.
If you are going to take up bird watching, trust me, you will love it. Binoculars are wonderful for any sporting events, or children's activities.
