Have you done the same tests for true aperture and magnification? They are easy to do. 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. 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.

Celestron 71007 SkyMaster 12x60mm Porro Prism Binoculars with

Celestron has been a revered manufacturer and competitor in the astronomy market since 1960. They produce telescopes, microscopes, and, most importantly, binoculars. BaK-4 prisms stand for Baritleichkron, which is a Barium Crown glass. BaK-4 prisms are superior to other types of optical glass as they produce more exact images. The decision to use BaK-4 prisms in the SkyMaster 12x60s allows less peripheral light to be lost through the internal reflection, decreasing light bleeding around the edges and allowing for a higher contrast image.Stargazing binoculars don't come much more perfect than these. The Celestron SkyMaster Pro 20x80 binoculars have huge magnification and massive objective lenses to get you closer to dimmer objects than almost any other binocular in our guide. The only thing Celestron's binos might have would be lighter weight and possibly flatter fields. Not gonna lie, I would love to do a side by side comparison of my 12x54s to those 12x50s!!

Celestron Skymaster 12x60 binocular review | Live Science

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. For beginning astronomers, birdwatcher enthusiasts, and everyone in between, Celestron's Skymaster 12x60 Binoculars are an excellent choice. Many reviewers were thrilled by the high quality provided at such a reasonable price. Next, a stargazing binocular should have generous magnification. We'd recommend upwards of 10x and ideally 15x or 20x plus. The greater the magnification the more detail can be observed in smaller constellations, asterisms, galaxies, globular star clusters and other celestial bodies. 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 It is possible to attach the double eyepiece cap (providing your own material) but not the objective lens caps. Not a deal breaker if you are careful with your binoculars, but something to be aware of if you plan on stuffing them in and out of your bag where they might get scratched. Should you buy the Celestron SkyMaster 12x60 binoculars?

High magnification views and big lenses make the Skymasters ideal for stargazing or getting a view of far-away subjects, even into twilight hours, but you'll need a tripod.

Well, you are right that if I measure the outside aperture of my 12x60s with a ruler it will come out at 60mm. But from shining a laser through the eyepiece of them and measuring how the disk of light that comes out the aperture I get 54mm. So there is an internal baffle. As for the exit pupil figure, I measured mine at 4.5mm which is what it should if I've only really got 12x54s. So honesty in one area and not so much in another.
