Combining a high magnification and oversized objectives, the Celestron 10x50 Ultima Porro Binoculars is an ideal optic for making detailed observations at long distances, even in challenging lighting conditions.

The large lenses draw in copious amounts of light and, combined with the 10x power, translate to a comfortable exit pupil that will completely cover most fully dilated pupils in low-light conditions, such as those at dawn or dusk and when peering into heavy brush or canopies. Complementing these performance features are anti-reflection fully multicoated optics, a wide field of view, long eye relief, and a traditional Porro prism optical path that all work together to produce an immersive and comfortable observational experience, featuring bright, clear high-contrast views with accurate color rendition and a rich depth of field. The wide field of view helps to mitigate the appearance of distracting hand shake that is common with higher power optics, for clearer views.

For long-duration glassing sessions, to reduce arm fatigue, or to eliminate vibrations, the Ultima binocular can be tripod mounted using an optional adapter. Its optical tubes are nitrogen filled and O-ring sealed to a waterproof IPX6 rating and resistant to internal fogging and the chassis is made of a lightweight and durable aluminum alloy and wrapped in a protective slip-resistant armor. Fold-down rubber eyecups mold themselves to your eye sockets to block stray peripheral light for brighter views without intrusive side glare, and the binoculars' center-focusing wheel is also slip resistant to make precision focusing fast and easy.

Q: 1. Made in China or Japan

A: They are Zuiko optics. The best in the industry. Who cares where they are made. . . . I'm pretty sure they are Japanese manufactured, but they are not marked.

Q: 2. Can these binoculars be mounted on a tripod?

A: They can't be mounted on a tripod using the Nikon mount that screws into the end of some Nikon models. I found that out the hard way. I actually bought the monarch mount with the binoculars (pictured) and then realized the end didn't screw off of the hinge...There are other universal strap mounts I have pictured and those will probably do..

Q: 3. are these FULLY MULTICOATED lenses?

A: Yes, the Opticron 6x30 Savanna WP Porro Prism Binoculars feature Fully Multicoated lenses.

Q: 4. I purchased a pair of 10x50 Celestron Nature DX ED binoculars and the Celestron Binocular Tripod Adapter. It is not obvious how to connect them, since each of these has a male 1/4-20 screw. There is not a female-to-female adapter to connect them, except for a very thin nut, which may or may not be 1/4-20 (it is very loose on the male threads). Is there a more detailed diagram showing how to mount the binoculars on the tripod adapter?

A: I figured out the problem. The logo cap that is described in the manual is firmly attached to the binocular's female threaded screw. Thus, when I tried to remove the logo cap the female threaded screw was coming off with the logo cap. Once I was able to separate the logo cap from the female threaded screw (with quite a bit of effort), I was able to thread the screw back onto the binoculars, allowing the tripod mount to be attached. Unfortunately the manuals provided by Celestron don't show enough detail for the user to see what the female threaded screw should look like.

Q: 5. Is a strap included?

Q: 6. Hi, I want to know that in the description AAoV is mentioned 65.4 degrees but in the specs, it is 8.2 degrees. It is correct or different?

A: It's simply the different values produced by the calculation for apparent field of view and those for calculation of the actual field of view. Sincerely, Garrett at Celestron
