Um, if you divide 60 into 10 parts, you get 6. and if you say take away one of those ten parts (which is equal to six) from 60, you get 54. I've done the light/laser test and it's true that they are truly 12x54s.

Remove the cover on the central pivot to expose the tripod adapter mount. (Image credit: Tantse Walter) If preferred, you can buy a tripod for more comfortable viewing or a smartphone adapter to permanently capture amazing sights. By default, the SkyMaster 12×60 Binoculars come with a carrying case, strap, microfiber cleaning cloth, and covers for the eyepiece and lenses. Bright Images in Dim Conditions It’s difficult for individuals with glasses to find binoculars that aren’t uncomfortable or have a shorter-than-average eye relief distance. The folding eyecups, dynamic diopter adjustment, and long eye relief distance are all ideal for overcoming optical difficulties.Multi-coated optics and high index BaK-4 prisms enable powerful light-gathering capabilities. Standard binoculars magnifications fall between 7x and 10x, while these SkyMasters go up to 12x. Featuring ED (Extra-low Dispersion) glass in its construction to improve contrast and reduce chromatic aberration and multi-coated lenses with it, the result is eye-popping image clarity, particularly when examining closer celestial objects such as the Moon. An objective lens diameter of 60mm means that it has an exit pupil size of 5mm. The exit pupil size determines the amount of light available to your eye. A 5mm exit pupil is sufficient for daytime and twilight use. Eyeglass Friendly Design Anyone who has worn glasses is familiar with the frustration and discomfort of looking through viewfinders, telescopes, and binoculars. All of the binoculars in the SkyMaster series feature folding eyecups, which means that they can be easily manipulated to the user’s preference. Celestron has been a revered manufacturer and competitor in the astronomy market since 1960. They produce telescopes, microscopes, and, most importantly, binoculars.

These mammoth binoculars are likely too big and heavy for many generalist observers. For those we’d recommend the recently reviewed Celestron Nature DX 12x56 because of their broader appeal given that they are of roof prism design and therefore more slender and lightweight. For a more compact pair of more generalist binoculars, consider the Celestron TrailSeeker 8x42 which we reviewed. They are among the best roof prism binoculars on the market. They have similar basic specifications but also the bonus of being nitrogen purged and waterproof. As we discussed earlier, they are roof prisms, which are inherently more compact than the Porro pair in this review. These high-powered binoculars also feature fully waterproof housing, interchangeable eyecups, superior wide-angle viewing, and are fogproof to protect against internal fogging in differing ambient temperatures. The 12x magnification and large 60mm objective lenses are excellent in low light and especially good for stargazing when mounted to a tripod. The optics are multi-coated, top-quality glass, with long eye relief and excellent build quality. Included Limited Lifetime Warranty protects against manufacture faults and defects in materials. If the Celestron SkyMaster 12x60 binoculars aren't for you Diopters correct the differences in the focus between the two binocular barrels, allowing compensation in eye strength variations. Not only does this result in a clearer image for the user but it also reduces the chance of eyestrain and headaches. Many binoculars carry a diopter range from -4 to +4, but the Celestron 12x60's range is a generous -4 to +8, allowing for stronger adjustments for weaker strength eyes.What sets these 'Pro' versions apart from their standard 20x80 counterparts down below is that they have Celestron’s proprietary XLT coating technology for clearer views of the cosmos. Many of the features are ideal for astronomy but can be used in other environments as well. The SkyMaster 12×60 model is more than capable of long-range terrestrial viewing in regular lighting conditions. Moreover, the aluminum chassis is both water and fog proof, which is beneficial for anyone exploring a humid area or moving through various elevations with different temperatures. Sky-High Rating by Other Buyers Despite that, these binoculars could serve as a great starter pair for a kid or young adult as they come with a padded carrying case and offer ample magnification at 10x and an objective lens diameter of 50 mm. Eyecups are adjustable and twist up or down. Users report some eye relief adjustments weren’t as easy and some quality control issues may not be noticed due to the lower price point. How we test the best binoculars for stargazing Featuring a rubber casing that helps with wear and tear, these binoculars come in at the lower end of the pricing model scale. Because of this, they are not waterproof and sacrifice a lot of the dim light conditions features you will find in pricier, astronomy-focused models.

Released somewhat recently in 2018, these mid-range Nikon binoculars feature lower magnification capabilities but have a generous objective lens diameter and roomier eye relief than other models. We reviewed the Nikon Prostaff P3 8x42 which is very similar to the 3S 10x42 noted here and gave them four out of five stars for their premium-finish and excellent clarity. If oberwerk chart informs that is 90% of objective area, the count should be square root of (60 * 60 * 0,,9) = 56,9, but if them say is 90% of their objective size, the count should be 60 * 0,9 = 54. I am talking about maths.The SkyMaster series of binoculars have multi-coated optics and high index BaK-4 prisms for superb light transmission and increased contrast and resolution. Coupled with large objective lenses, BaK-4 prisms offer amazing light gathering capabilities making them ideal for stargazing and other low-light applications. With higher magnifications than standard binoculars, SkyMaster 12x60 brings celestial objects up close, providing images with outstanding detail.
