There’s also a slightly higher priced 10x42 alternative available too and likewise covered here. The suggestion is that the 10x30 matches the 10x42’s performance – and in a more compact form. The HD lens system provides superior image clarity and color fidelity. Cut the chromatic aberration to render color-corrected image output every time. The body is made of quality aluminum. So the rugged construction ensures that they can withstand even the most extreme conditions. The larger the aperture, the easier it will be to see fainter night sky targets such as galaxies and nebulae. As a rule of thumb, and under decent observing conditions, 7x35 binoculars will reveal a hundred thousand stars and 10x50s will show the finer details of the Moon, planets, Andromeda Galaxy (Messier 31) and the Orion Nebula. Larger, heavier binoculars such as 20x80s and 20x100s, will open up a wealth of objects such as the fainter spiral galaxies Messier 65 and NGC 3628 and a selection of globular clusters and star-forming regions. Although it's impossible to see much detail in the giant planet's cloud-tops, we could easily discern Jupiter's four big moons Ganymede, Europa, Callisto and Io. When trained on Polaris, the North Star, we were treated to a sharp view of the 'engagement ring' of nine stars around it. Ditto the stars of the Beehive Cluster in Cancer, from which we got immersive and contrast-heavy views, with only a slight drop in sharpness detectable towards the edge of the field of view. It's barely noticeable, only being an issue when sweeping the Nikon Action EX 12x50 binoculars across the rich star fields of the Milky Way. Nikon Action EX 12x50 binoculars: Functionality

All of Canon’s current range of binos have the ‘IS’ suffix in their model name to denote the fact they’re image-stabilized binoculars. This battery-operated option enables you to get a wobble-free image by just pressing a button on the binoculars – and the stabilizing effect is both instant and jaw-dropping.BK-7 and K9 glass can be found in cheaper products, and refer to borosilicate formulations. While used across a wide range of brands, this glass is said to lead to problematic exit pupils — in particular the field of view isn’t perfectly round, which can leave the observer with poor clarity around the edges of their chosen target. We must stress that this isn’t true for all pieces of kit, so we advise giving your chosen binoculars a test before parting with your cash. Best binoculars for astronomy: If you're planning on stargazing, we'd recommend a binocular size of around 7x50. The 7x magnification will work well for Astro viewing as a compromise between the field of view and magnification, while a 50mm lens will provide plenty of light transmission for spotting fainter celestial objects. Notably, the most common binos in the market are in the 6x to 10x magnification range, and it’s understandable because they’re easier to use. They have less shake, images are clearer, and the field of view is typically quite large. When using the Celestron TrailSeeker 8x42 binoculars, you'll notice minimal false color. False color, which appears as a purple or blue halo around bright objects (also known as chromatic aberration), was hardly noticed in our review, especially when we were looking at the lunar limb. describes the refractive index as a measure of how much light rays bend as they pass from one medium to another. As for SK15 glass, it has a higher refractive index than both BAK-4 and BK7. However, the light dispersion falls between the two. SK15 prisms aren’t as common in the market as the other two. Ultimately, the upsides and downsides of these prisms and the types of glass they use should help you determine which binos to buy. Eye Relief

In our Canon 10x42L IS WP binoculars review, we thought that even though they are pricey, they are almost perfect for hand-held astronomy, so we believe the cost is justified if you can afford it. This roof prism pair of premium-feel binoculars delivers results that are truly outstanding, albeit for a price. That said they’re slim, lightweight and easy to use, while being fogproof and waterproof too, to depths of five metres for up to 10 minutes. Delivering the sort of sharpness that will satisfy the most demanding of wildlife watchers or birders – thanks in part to its ED glass construction – the 10x magnification wedded to 42mm objective lens provides good views into the twilight hours. Inevitably they’re slightly heavier and bigger than the closest 10x30 model in the same series, though.The glass is identical to those used in Canon camera lenses, and it has the 'L' designation that distinguishes some of the best and most expensive lenses ever to be used with a digital sensor. You can expect sharp, bright and stable views through these excellent binos. Pointing them immediately at some of the brightest stars and objects in the night sky, we failed to detect any traces of yellow and purple color fringing around while observing super-bright Sirius and a First Quarter Moon. Meanwhile, the dozens of stars within the Pleiades star cluster looked uniformly sharp, almost to the very edge of the field of view. We have selected another Nikon binocular for you for its amazing features and outstanding performance. The Nikon Aculon A211 12×50 binoculars offer a powerful magnification for an incredibly clear view. Also, the bigger objective lens is responsible for gathering light to generate bright and sharp images.
