Product Information

At the typical temperatures of night-sky observing, the surface feels quite cold to the touch. That's actually a good thing. It suggests these Celestrons will "equilibrate" (cool) to ambient temperature faster than better-insulated binoculars. This isn't as big a deal as it is with telescopes, especially mirrored ones ( Newtonians and Cassegrains), but it's nice for all your optical surfaces to maintain their relative geometries. The moon appears stunning through these binoculars, easily fitting within the field of view with only a slight hint of false color. In July 2020, the UpClose G2 10x50 binoculars proved to be an excellent tool for observing the naked-eye comet C/2020 F3 (NEOWISE). The Nikon Action EX 12x50 binoculars are a great alternative to the typical 10x50 binoculars because they offer a larger 12x magnification and the same 50mm aperture. The construction is outstanding, with comfy rubber grips and a big focus knob. Eye relief is 0.51-inches (13 mm). The Argus in my eyes proved better in this than the Nightstar and the Skymaster, but all three provided reasonably good ease of view. The two Omegon models provide 3mm more eye relief than the Celestron, but I did not feel that difference to be very relevant (I observe without glasses, so this may be relevant for eyeglass wearers).

Whilst it is possible to hand hold a 10x70 or even an 11x80 for short periods of time (by grasping them around the barrels near the objectives), they will become too heavy to steadily hold up to your eyes for any meaningful length of time for proper observation. Some models of binocular will have their field of view printed on the barrels or somewhere close to the magnification and aperture. Given in degrees, this number tells you how wide you can see when peering through the eyepieces. The larger the number, the wider the scene. Ten degrees will allow the Big Dipper’s bowl to fit comfortably in your field of view. Which is best BaK-4, BK-7 or K9 binoculars? The Celestron 25×100 SkyMaster binocular offer 25x magnification and a very large 100mm diameter objective (like having a pair of four inch refractors!). To maintain secure optical alignment, and for maximum stability, these 100mm SkyMaster models feature enhanced structural reinforcement to the main binocular body.

They also feature individual eyepiece focusing for optimal focus position for each eye. Since you're magnifying the same amount of light collected by 10x50s, a higher magnification usually means images are less bright. Despite the loss of brightness, the Action EX 12x50 is equipped with multi-coated lenses and high-refractive-index prisms to ensure that the decrease in brightness isn't noticeable. In our Nikon Action EX 12x50 binoculars review, we found that you get great, high-contrast images. With its rings not resolvable on their own, Saturn was a challenge for this pair of binoculars. However, skywatchers will detect definite ansae, or the extension of the rings at either side of the planet, giving Saturn an oblate shape.

Most brands offer 5 to 10 years these days, with many offering lifetime guarantees.These binoculars produce clear, focused images in the center of your field of view when viewing stars. While observing the Milky Way or larger star clusters, you could become distracted by some curvature as you shifttowardthe edges of the5.5-degree field of view. Overall, the Skywatcher Action EX 12x50 provides an excellent observing experience. They're brilliant for astronomy but also perform well across a wide range of observation environments. These heavy-hitters are certainly not for the uninitiated binoculars-users. Despite being labelled as such, we've already mentioned that they're more like two 100mm refractor telescopes glued together and they give enormous reach. Therefore, they're not suitable for handheld use as it'd be too hard to keep them steady and would end in arm ache.
