Most binoculars are multipurpose instruments. Astronomy stores are accustomed to dealing with the confused beginner though of course not everybody has the opportunity to visit a specialist store.
The bashability of binoculars refers to how tough they are. First, determine just how and under what circumstances you will be using your new binoculars. Many binoculars have eyepieces that fold in and out.
There are giant binoculars available with higher magnifications and apertures which are designed for astronomy use but you will certainly need a sturdy tripod or mount to use them. That is to say, different users with different space between the eyes will be able to view the reticle horizontally. The range of you binocular depends on three things, its gain, resolution and magnification.
Quality night binoculars have an infrared illuminator which increases the available infrared light. If performance is your main consideration, full sized binoculars are preferred. Mars and Venus on the horizon are a whole different picture when you can magnify your own vision.
There is no such thing as one-size-fits-all when it comes to sporting optics. You will also need to buy an atlas of the sky suited for astronomy, and a guide.
