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. Using binoculars is not a risk free activity.
High power spotting scopes, or binoculars, where the power exceeds 10x will need to be mounted on a tripod. The same goes for hunting binoculars, and in both cases they should be lightweight, but probably with a smaller magnification, and larger objective. Boaters and those that enjoy the water will want the waterproof or fog proof models.
A telescope allows the universe to come to you, in other words objects of long distance come closer, while a microscope puts small objects to become bigger so you can see. As with the aperture of a camera lens, the size of objective lens determines the amount of light that can enter your binoculars. While the Leupold 10x50mm tactical binoculars are great for tactical operations, it is no loser to hunting and shooting sports and bird watching and observations.
Most pocket binoculars also feature long eye relief. One fascinating use of binoculars is looking at the night sky. Some of the binoculars have a greater close up focus capability.
Let's face it, you are going to possess these binoculars for a long time, so get a good pair. You will also need to buy an atlas of the sky suited for astronomy, and a guide.
refracting nasa telescopes - just like the ones that dad and his friends used to have
