leather binocular cases - beginner's instructions

Over the last few hundred years, the telescope has been an instrument which has allowed the heavens to come into our doorstep. The image seen through monoculars appear in their correct orientation through the use of two prisms, whereas in most telescopes the images are inverted.

Tasco binoculars, Bushnell binoculars and Nikon binoculars are three of the most popular brands in the marketplace. For most uses, 8x is a good magnification to choose. For most uses, look for a objective diameter that is five times the magnification power.

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. Size is dictated by the objective lens.

Field-of-view is determined by magnification and the focal lengths of the objective and eyepiece lenses. Many of us have looked at the moon through binoculars. Those new to the game should consider obtaining a pair of binoculars that posses a large field of view.

Binoculars allow you to take in all of the details from a distance. You'll see everything clearer and you won't want to travel without them.
