Before you decide how to choose binoculars you need to consider the solutions for differing environments. Raise binoculars to your eyes and you can see everything far away as if it was right in front of you.
When you look at objects in the night sky, they are constantly revolving in its path, this makes objects move in the night sky. You position your telescope to look at the Moon, you see craters, and find that soon as you go to call someone to take a look, they take a look and it is gone. Many people prefer to carry binoculars around freely, rather than in a case.
They suck dirt off the lens surfaces leaving them crystal clear. That is to say, different users with different space between the eyes will be able to view the reticle horizontally. A pair of binoculars that reads 7x50 can magnify things seven times stronger than they actually are with a 50mm objective lens.
Looking in the two to five hundred dollar range when buying binoculars is the best for your money. Everyone asks how to understand the magnification on binoculars. You may not be planning on getting them wet, but things happen; you might trip and drop them in a mud puddle, take them out on a foggy day, or you might get caught in a freak rain shower.
You want to keep these for years to come so you might as well be comfortable. The newer binoculars are very lightweight making them ideal to pack in your lightweight luggage.
