The need for using sophisticated equipment for viewing the stars has limited the number of participants. Before purchasing a telescope it is very important to know what you want and what.
While cleaning your binoculars, you should take care to see that no cleaning mark or scratch is left on the surface of the lens. As an experienced wildlife photographer my top priority was optical quality, and I did alot of research before deciding on this pair. If you are a backpacker or will be doing your birding on a bicycle, then you may wish to consider mid size or even compact binoculars.
A good rule of thumb is, unless you are a private investigator or international spy, avoid buying a pair of binoculars with a magnification/zoom greater then 10x's. A 7 x 50 binocular shows a view magnified 7 times and it has objective lenses 50 mm wide. It is also useful in ranging an object that is not perfectly horizontal or vertical, enabling you to determine the range without tilting the entire binoculars.
A field-of-view of 390' indicates that the width of the sight picture is 390 feet at a distance of 1000 yards. The lower priced binoculars are generally cheaper because they have a lower field of vision and are made with cheaper lenses. You can even achieve getting advice about telescopes online, you can look at reviews, you can email a telescope seller or give them a quick call to get more information.
Now it is time to get outside. Treat your kids to a pair of inexpensive binoculars to explore the natural world around them.
