locking diopter, the B1 Plus features enhanced optical tolerances to
provide even sharper images and greater optical performance. Redesigned
exterior rubber armor gives the user a more solid grip, contoured to
better fit in the hand for comfortable use in the field.
- Premium European Optics
- Aluminum Alloy Body
- MeoBright Coatings for Optimal Light Gathering
- Fluoride HD lens elements in 10x42, 12x50, and 15x56
- Locking Diopter Adjustment
- Ergonomically Designed Rubber Armor
Designed
to be your go-to optic for long-range/low-light use in wide open and
expansive terrain, like the plains of the American West, the Meopta 15x56 MeoStar B1 Plus HD Binoculars
provides a superior viewing experience by combining well-engineered
optics and a wide field of view with a lightweight and durable ergonomic
housing.
The pairing of massive 56mm objectives with powerful 15x
magnification produces a comfortable eye relief that ensures you won't
get eye strain if you spend long hours looking through them. Extra-low
dispersion (ED) fluoride glass lenses, treated with proprietary
MeoBright multicoatings, and compact Schmidt-Pechan prisms deliver vivid
true-color images that are bright and crisp even when observing small
game at extreme distances or when you're scanning the landscape at first
light or late dusk. The lenses are further treated with Meopta's
proprietary MeoShield and MeoDrop exterior coatings that protect them
from scratches and makes cleaning oils and other contaminants easy
without leaving residue. These coatings ensure the lenses stay free from
imperfections that can interfere with your glassing experience and let
you immerse yourself in the view.
Meopta designed the binoculars
with ergonomics in mind to minimize user fatigue during long
observations. Its large center focusing wheel is easy to use with either
hand and a locking dioptric correction dial, located on the focusing
knob, ensures precise focusing even if you normally wear corrective
eyeglasses. The housing is made from a lightweight and durable aluminum
alloy that is center weighted by the prism design, so they sit
comfortably in the hand. Protective rubber armor wraps the body and
provides a slip-resistant grip, especially in cold and wet conditions.
The housing is nitrogen filled and sealed to be waterproof and resistant
to internal fogging in extreme conditions.
Optical Performance
- Designed
for use in wide and open terrain such as is found in the American West,
where extreme long-distance observation and identification are common
- Powerful 15x magnifies the view, allowing detailed observation and identification of distant subjects
- Massive
56mm objective lenses draw in the large amounts of light required to
deliver bright views in pre-dawn or deep dusk or when observing subjects
at long distances
- Schimdt-Pechan roof prism design allows for
thinner optical tubes versus the more common Abbe-Koenig design,
resulting in an easier-to-hold form factor without compromising
performance
- Extra-low dispersion (ED) fluoride glass objective
lenses correct chromatic aberrations and fringing to deliver bright and
clear high-contrast and high-resolution views with accurate color
representation
- Proprietary ion-assisted MeoBright multicoatings deliver 99.7% light transmission while suppressing glare
- MeoShield exterior coating protects lenses from scratches or abrasions
- MeoDrop
lens coatings repel water and allow grease, skin oils, and surface
contaminants to be removed without residue that can impair view clarity
- Wide
63° apparent angle of view provides sweeping views of the terrain with
reduced appearance of the distracting hand shake that is common when
holding high-power optics
- Generous 221-foot field of view at 1000 yards
Use and Handling
- Closed-bridge configuration provides a solid and stable platform for the internal focusing mechanism
- Large
slip-resistant center focusing knob with ±3 dioptric correction dial is
easy to manipulate in cold and wet conditions, even while wearing
gloves
- Locking diopter sets the desired correction against accidental adjustment
- Wide 56-74mm interpupillary adjustment range
- Twist-up rubber eyecups for easy use with or without eyewear
- 15mm eye relief reduces eyestrain during long glassing sessions
- 3.7mm exit pupil

B1 15X56 HD Binocular Q&A:
Q. Is this MeoStar a long range hunting binocular?
A.
This 15X56 HD MeoStar is an excellent tool for long range hunting. In
fact, it’s designed for the extreme ranges. This is usually the
magnification range where rifle scopes end and binoculars excel at.
While
hunting, you’ll be able to range your area well beyond 1000 yards with
ease. If you’re actually shooting at these distances, then you’re going
to need to make sure you have just as capable equipment to make that
shot.
Perhaps, an extreme long range rifle scope picked from one of our Rifle Scope Reviews?
This
binocular is also going to perform very well not only for hunting, but
for nature observing and perhaps some astronomy as well.
Q. Is this a good binocular for low light hunting?
A.
The 56 mm objective lens size might indicate to you that it’s an
excellent low light binocular. But, let’s take a peek at the techs and
specs to further analyze its capabilities.
With
a 56 mm objective lens and 15X magnification, the math tells us that
the exit pupil is 3.7 mm. Hmm.. From what we know about pupil dilation
and dark conditions, the human pupil should be able to open up anywhere
between 4 and 7 mm. Although the 56 mm objective lens might be larger to
allow in more light, the exit pupil isn’t large enough to let it all
through.
So, you’re really not getting maximum use of the large objective lens in the end.
However, if you can get your hands on a MeoStar 8X56 HD
model, you’ll be able to get up to 7 mm of exit pupil. It might still
be a little much for your eyes anyways, but that’s better than the 3.7
on the 15X56.
Unfortunately, you’re paying for the larger exit pupil by compromising your twilight factor capacities.
You
still have to remember that the twilight transmission of 85 percent and
the twilight factor of 29 are still decent figures. In the end, the
difference that’s going to matter in making this a great low light hunting binocular is the quality of the glass.
All
other aspects aside, if you have superb glass that’s the best of what
you can get, that’s going to be more useful to you than any math,
percentages, and comparisons.
Q. Has the MeoStar 15X56 HD binocular been recognized?
A.
How could this binocular not? It’s so big that you can see it from a
mile away. It attracted the attention of Gray’s Sporting Journal and won
the prestigious award of Gray’s Best Winner for 2016.
For
a bino that was just released into the market in 2015, this is a very
deserving award it has earned, never mind the fact that Meopta could use
the spot light to get its name out there.
Q. How big is the Meopta binocular?
A.
I’ve been giving this MeoStar a hard time because of it’s
magnification+objective lens size combo, but let’s actually take a look
at its physical dimensions. It’s 7.87 x 5.59 x 2.36 inches.
Okay,
this bino barely squeezes into the standard size pair of jeans with
maybe a little bit of a muffin top – way to go. It’s not as big as I’ve
made it out to be.
And,
as a fun way to redeem myself to the 15X56, let’s take a look at the
8X56 model, you might just be a little surprised. Its dimensions are
8.03 x 5.59 x 2.52 inches – just slightly bigger than the 15X56.
But,
this bino is still heavier at a whopping 43.28 ounces, and that’s not a
bad thing. All that bloat is fully justified, thanks to the extra glass
of the 15X magnification.
Q. Is this binocular tripod adaptable?
A.
Yes, and with 15X magnification, you’d hope so too. With such high
power hand-held optics, you’ll notice it’s more difficult to keep a
steady image. Even if you don’t have shaky hands, the slightest tremors
of movement will keep the image in a constant wiggle. Enter here – the
convenience of tripods.
The
other nice thing about the heifer weight of the bino is that because
it’s heavy, it has enough poundage to maintain its position on the
tripod. Sometimes too light and compact of a binocular isn’t a
tripod-friendly device.
It’s light frame and weight would be too vulnerable in the wind or really any imperfect weather conditions.
