Binoculars – Every stargazer should own a pair!
We think of telescopes when looking at ways to explore the night sky. But binoculars are more useful than telescopes in many situations. They come in various shapes and sizes. Which ones are good for astronomy?
Choosing The Right Size
Size matters when it comes to choosing binoculars. Basically, the bigger they are the more magnified or closer the image will be. Small binoculars (less than 10 x 50) aren’t really much good for astronomical use. Smaller pairs tend to be more useful for terrestrial observing like bird spotting etc. The only caveat with larger binoculars is you will need a tripod to support them and keep them steady. Handheld use is only really doable for short periods.
Larger/ stronger magnifications can narrow the field of view compared to less magnification. Therefore the image in a pair of 25 x 75 binoculars will be narrower than that of a 15 x 75 pair. This is a personal choice, however. Magnification is the first number when describing binocular size e.g 15 x. The second number is the size of the individual objective lenses (bigger lenses on the front) e.g x 75. Larger/ ...
