As it is with binoculars, so it is with scopes. Astronomy stores are accustomed to dealing with the confused beginner though of course not everybody has the opportunity to visit a specialist store.
You should always use a professionally made binocular lens cloth to clean them. High power spotting scopes, or binoculars, where the power exceeds 10x will need to be mounted on a tripod. The most advanced binocular lens cloths are made of microfibre.
If you are using binoculars with a large, heavy objective lens it is helpful, if not necessary, to stabilize them by either resting them on something or mounting them on a tripod. 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.
But still, a good pair of night-vision binoculars will cost at least a thousand dollars. Low light uses such as hunting, birding and astronomy require larger objective lenses. Coupled with the size of the objective is the light gathering ability of the lens and the field of view.
Binoculars are wonderful for any sporting events, or children's activities. Get a good pair and enjoy!
