[It’s commonly recommended that, before you buy a telescope, you should first get a pair of binoculars. And with very good reason! Not only are such glasses much less expensive, very portable, and always ready for immediate use, but they can also provide views of the heavens unmatched by any telescope. This results primarily from their incredibly wide fields of view — typically 5 or 6 degrees (or 10 to 12 full-Moon diameters) in extent compared with the 1-degree fields of most telescopes, even used at their lowest magnifications. There are also ultra-wide-field models that take in a staggering 10 degrees of sky. Binoculars are ideal for learning your way around the heavens and for exploring what lurks beyond the naked-eye star patterns.]
