Binoculars repair is the last thing on the mind of a user as they purchase their prized tool. Here, since they are, in effect, half the size of a regular pair of field glasses, better quality optics can be afforded, as the cost will be proportionally lower.
Some are too powerful, and others not powerful enough. And, if you are in the military, then the Leupold Scope Tactical Binoculars may just be your best binoculars buy. For astronomy use you will need at least 40mm aperture and preferably larger.
If you will be staying in one spot for a period of time then it might be to your advantage to consider mounting the binoculars on a tripod which would free up both hands and not require you to find the viewing area, refocus, and keep steady each time you pick them up. I've used them for about three weeks now and have been blown away with the quality of the optics. Quality night binoculars have an infrared illuminator which increases the available infrared light.
Many binoculars have an option for attached lens covers that open and close as you make your observations. Some have special fire coating employs advanced technology that is designed to eliminate both infrared light and ultraviolet rays. In most cases, pocket binoculars are of prism roof design and the front lenses and the eyes come in a straight line; such binoculars are usually compact.
Binoculars that have built in digital cameras are becoming increasingly popular among photographers, bird-hunters and those spies we mentioned earlier. Your willingness to increase your budget will often provide you with a return in performance of your purchase.
