Model numbers on binoculars essentially tell you their strength (magnification power) and size (objective lens diameter). In 8×42 binoculars, for example, “8” is the magnification power and “42” is the diameter (in millimeters) of the objective lenses (the lenses closest to the object you’re viewing).
Similarly, What does 12×50 mean on binoculars? “12X” refers to the magnification of a pair of binoculars while “50” refers to the lens diameter in millimeters. Therefore, a 12X50 bino means that it has 12X magnification and 50mm lens diameter.

Beside above, What is a good binocular magnification? Generally, binoculars with a magnification of 6 to 10x are easier to use, but for birdwatching, tracking moving objects, and keeping shaking to a minimum, 8 to 10x magnification is best. For theatergoing, a somewhat lower magnification is easier to use, and portability is an important factor.
What does 8×42 mean in binoculars?
These refer to the magnification and objective diameter. An example is: 8×42. This indicates the magnification of the binoculars is 8x power and the objective (front) lens is 42mm in diameter. The natural tendency for most people new to binoculars is to get the most powerful binoculars they can find.

Can Saturn’s rings be seen with binoculars? Binoculars will enhance its color, and even a small telescope will let you glimpse Saturn’s rings. Veteran observer Alan MacRobert at SkyandTelescope.com has written: The rings of Saturn should be visible in even the smallest telescope at 25x [magnified by 25 times].
What is a powerful binocular? The Sunagor 30-160x70s are widely believed to be the World’s most powerful pair of binoculars. At their starting point of 30x magnification, they already offer an above standard level of power found only on much more specialist binoculars.
What does eye relief mean in binoculars?
Eye relief is the distance from the outer surface of the eyepiece lens to the position where the exit pupil is formed (eyepoint). Looking through binoculars from the eyepoint, you can obtain the whole field of view without vignetting.
What’s the difference between 8×42 and 10×42 binoculars? This difference between the two can largely be explained by the relationship between the size of the pupils in your eyes and the size of the shafts of light exiting the ocular lenses (exit pupil) of the binocular: 8×42 binoculars create a 5.25mm exit pupil (42/8) 10×42 binoculars create a 4.2mm exit pupil (42/10)
Are telescopes better than binoculars?
Telescopes are not inherently better at looking into space than binoculars. Yes, astronomers’ telescopes, with their gigantic lenses and sturdy support systems, are more powerful than binoculars you can carry. But it just comes down to size. Both tools rely on the same optical principles to do the job.
Is 8×42 better than 10×42? If you need a good, general purpose pair of binoculars, then you can’t go wrong with an 8×42, which excels in most categories. But 10X42 binoculars have their place as well. The higher magnification means you can see more detail in your subject and even view subjects that are farther away.
Which is better 12×50 or 10×42 binoculars?
The magnification power of a 12×50 is 12 times magnification (12 times larger than normal unaided vision). So the “zoom difference” would be an increase of 20% in the magnification from a 10×42 to a 12×50.
How far can 20×50 binoculars see?
The 20x50mm have a close focusing distance of 45 feet. Anything closer than 45 feet is going to appear blurry.
Is 10×42 better than 8×42? If you need a good, general purpose pair of binoculars, then you can’t go wrong with an 8×42, which excels in most categories. But 10X42 binoculars have their place as well. The higher magnification means you can see more detail in your subject and even view subjects that are farther away.
Is 10×50 better than 8×42? There is a big difference when it comes to the field of view: 10×50 usually gives you 110 m / 1000 m of field of view, and with 8×42, they have fields of view starting at 130 m / 1000 m to 160 m / 1000 m. So, you gain a lot of field of view with 8×42.
Are 8×42 binoculars good for bird watching?
The consensus is that 8X42 is the best all-around birding binocular “size.” Additionally, birding binoculars should be durable, provide crystal clear views, and not break the bank.
Can you see moon with binoculars? Whether your tools are a telescope, a pair of binoculars, or just your eyes, you can find plenty of features on the Moon. We only ever see one side of the Moon from Earth. That’s because the interplay of gravity between Earth and Moon slows the Moon into a rotation that paces its own.
Can you use a telescope as binoculars?
So, in a nutshell, yes, you could turn a telescope towards objects here on Earth instead of a pair of binoculars, and it would work, but for best results and easiest performance, use binoculars instead.
Can you see ISS with binoculars? International Space Station and satellites
People are often surprised to learn you can see the International Space Station with just binoculars but it’s actually visible to the naked eye. When visible it’s the 3rd brightest object in the sky!
What does Mars look like through binoculars?
Mars. The red planet really does look red, and binoculars will intensify the color. Mars also moves rapidly in front of the stars, and it’s fun to aim your binoculars in its direction when it’s passing near another bright star or planet.
Can I see galaxies with binoculars? A good pair of binoculars can give you a new perspective on some wonderful objects in the night sky, including the moon, planets, double stars, star clusters and nebulae, and even galaxies.
