Fact #1. Humans have had an interest in astronomy since ancient times. Prominent Greek writers as far back as the 7th century mention identifiable stars and constellations in their work. Homer mentions the constellations Orion and Ursa Major in the Iliad and the Odyssey, along with the star cluster Hyades and Sirius, the dog star.
Fact #2. Civilizations such as the ancient Chinese and Mayans used astronomy to orient their cities and track time as early as 2000 BCE. Records also show evidence of some civilizations trying to use astronomy to predict the future. Most early forms of astronomy incorporated both careful study of the night sky and religion.
Fact #3. Telescopes have traditionally been the go-to device for viewing the heavens. However, binoculars offer a few distinct advantages. One of the biggest drawbacks of telescopes is their size. Even a small telescope is much larger than your average pair of binoculars. This seriously hinders their portability.
Fact #4. One of the greatest advantages of binoculars comes from their very design. Unlike a telescope, with binoculars you get to view space with two eyes. This is very important to give your brain the full visual experience. Not only does single-eye viewing severely hamper your depth perception. It also decreases your signal-to-noise ratio. When you have a high signal-to-noise ratio, your brain filters out much of the unwanted random impulses from each eye. This leaves you with a better view of whatever objects you're looking at.
Fact #5. The most prominent specification notated on binoculars, and one of the most important, are the numbers representing magnification and lens diameter. Some models also have an adjustable zoom feature. This allows you to adjust the magnification to your needs. Another important specification to pay attention to is field of view. If you prefer the immersive space walking experience, choose a model with a wider field of view.
