When you remove the binoculars from the packaging, the first thing you’ll immediately notice is that these binoculars are not small or light with an aperture of 80mm, it’s like holding two small telescopes up to your eyes. (Incidentally, if you happen to drop them, they may need collimation, and while a temporary fix may be attempted by experienced observers, beginners would be best advised to leave this to an expert.) 1 Ease of Use
Overall, these binoculars are sturdy and solidly built, and while it’s never a good idea to subject them to a knock or two, they should hold up well in the event of an accident. This means they’re safe from the rain but probably won’t stand up to being immersed in water. Lastly, it might be worth pointing out that these binoculars are water-resistant, not waterproof.

On a related note, the aperture test yielded the full 80mm, so you can be sure you’re getting the full field of view. Holding the binoculars up to the light, the exit pupils appeared sharp and circular, with no visible clipping, confirming the presence of the BaK-4 prisms within. Specifically, this allows for a crisper image around the edge of the field of view. The prisms are BaK-4, which are a better quality than the BK7’s you might find in cheaper or inferior products. According to Celestron’s blog, fully multi-coated lenses provide a light transmission rate of 90-95%. Full multi-coated lenses have all glass surfaces coated multiple times. What’s the difference? The lenses are coated to reduce light loss and glare multi-coated lenses mean the lenses have been coated multiple times on at least one surface. For example, the lenses on the standard 20×80 SkyMaster binoculars are multi-coated, while the Pro’s lenses are fully multi-coated. Quality & DurabilityĬelestron is a very well-respected manufacturer, and as you’d expect, these are very well-constructed binoculars, but the optics are not quite the same quality as the SkyMaster 20×80 Pro. This provides the covers a much tighter fit and prevents them from slipping off in the carry case. Meanwhile, unlike most other binoculars, the lens covers don’t fit over the apertures, but rather inside the apertures themselves, almost like plugs. The eyepieces have a single cover with a small loop, allowing you to thread the strap through and preventing the covers from dropping to the ground. This is not removable, but given the weight of the binoculars (see Quality and Durability below) you’ll soon realize that a tripod is an essential accessory for any observation session lasting a prolonged period of time. The first thing you’ll notice (even before you take them out of the packaging) is that there’s a tripod adapter attached. The binoculars themselves are safely and securely encased in foam for transport. (Some manufacturers are even more generic, so Celestron should be commended for at least making it specific to the range.)
You’ll also notice that it’s written for the SkyMaster range as a whole, rather than the 20×80 model specifically.
Zhumell binocular manual#
The user manual is relatively large in dimensions (8 x 11 inches) and yet the print is frustratingly small, so be sure to wear your glasses before attempting to read it! Unlike some other brands (and even certain other binoculars by Celestron) the case has no pockets, which is a shame since there’s certainly room for one on the back. As such, it won’t provide a lot of protection should the binoculars be knocked or even dropped. Inside, you’ll find the binoculars themselves, a canvas carrying case (with a shoulder strap already attached), a strap for the binoculars, a small cleaning cloth, and a user manual.īeing canvas, the case is soft and is designed simply for the purpose of allowing you to conveniently carry the binoculars with you. Most binoculars arrive in a plain package that gives little away about their contents, but Celestron has clearly made some effort here, with a nicely designed, attractive box. Bartlett About the SkyMaster 20×80 BinocularsĪs you might expect of binoculars this size, the packaging is neither small nor flimsy, with the box measuring 11 x 7 x 16 inches and the entire package weighing 6.8 pounds. Smooth focusing mechanism for sharp, colorful star views.Īll Photos Credit: Richard J.
