A pair of binoculars can be seen as two such telescopes, side by side, which together produce an image which has the depth of field that we are used to, rather than just a large flat image. So you've been bitten by the astronomy bug and want to get started with your very own telescope, but you're confused by the vast number of possible purchases?
The same goes for hunting binoculars, and in both cases they should be lightweight, but probably with a smaller magnification, and larger objective. When beginning a day of binocular observations, it is tempting to leave the binocular case in the car or at the base camp and rely on neck straps or other attachment mechanisms to secure the unit. The binocular rating has two basic parameters, magnification and aperture.
If your binoculars are going to be used during low light like hunting and astronomy, you had better have large objective lenses. Remember you get what you pay for, so ensure you buy a good quality pair to prevent disappointment in the field. Do keep in mind that a larger objective diameter will generally increase the size and weight of the binoculars.
The range of you binocular depends on three things, its gain, resolution and magnification. Binoculars are one of the handiest optical instruments and are necessary for hunters of all experience levels. When deciding to buy a telescope, ask yourself, how much room you have to house to telescope and what things do you want to look at with your telescope, deep space, local or both?
You want to keep these for years to come so you might as well be comfortable. Check the seals periodically, and bring your binoculars in for servicing if there are signs of cracks or leaks in the seals.
