Mount Options:

Requires either the Heavy-Duty L Adapter or the Adjustable Tripod Adapter (preferred).


Our lightweight 20x80mm is probably the best buy in the Oberwerk line, especially since it now includes a $45 rugged hard case from Royal Case of Texas! Giant 80mm objectives have a serious amount of light grasp, yet they weigh just 4 pounds! Fabulous for astronomy when used with a tripod, and light enough to be hand-held for terrestrial usage, such as wildlife observation and surveillance.

Low-reflection broadband multi-coating is used on every air-to-glass surface, including prisms. Light loss due to reflection and scattering is minimized, providing the highest level of light transmission possible. New “slow-focus” provides precise focus control that won’t drift. 18mm of eye relief means you’ll see the entire field of view even when wearing eyeglasses.

This model is somewhat “objective heavy”, therefore we highly recommend our new Adjustable Tripod Adapter, (instead of the Heavy-Duty L Adapter) which allows fore & aft adjustment, to obtain perfect balance on your tripod head.

New for 2018, the prism covers in between the body and the objective tubes are now aluminum, to more rigidly hold the objective tubes in perfect alignment.

All Oberwerk binoculars have rugged rubber-armored aluminum bodies, all-glass lenses, BAK4 prisms, right ocular diopter adjustment, fold-down eyecups, brass 1/4-20 tripod adapter socket, caps, and neck strap. Also includes a $45 rugged hard case. A remarkable buy at only $199.95.

    I just wanted to drop a note and tell you how happy my wife and I are with the quality – both optically and mechanically – of this great product. My reason for the purchase was for astro-viewing as a supplement to our telescopes (we’ve been using other brand binos for a long time), but since using them, we’ve found that they are our “first grab” for birding as well. The evening that they arrived, I stepped out on our back porch just as it got dark and took in a wonderful view of Jupiter and the 4 big moons. I called my wife our for a look and she was completely blown away! Neither of us expected such great performance for an relatively inexpensive pair of binos, especially at 20X. Color correction is excellent right out to the edge of the field, something I never expected form a relatively low cost pair of binoculars. We spent a great deal of time outside that night taking in the sights (we also had a telescope set up, though it didn’t get much use that evening). I was especially impressed at how well the binos were able to pull in the light from M31 in our light polluted sky. One of our favorite viewing targets, M45, is especially impressive through this wonderful instrument.

    Very happy with purchase, I have not used the binoculars much for astronomical use due to the weather I did sneak a quick look at Pleiades the view was fantastic. I would purchase a tripod for these as they get heavy handholding after awhile . I called Oberwerk with questions after the purchase all my questions were answered to my satisfaction very nice people to deal with.Looking forward to doing more business with Oberwerk.

    The Oberwerk 20×80’s are just what I hoped they would be. They came well collimated and perform very well. Near perfect star images. Kevin was so helpful in answering all my questions. I highly recommend him and his product!!

    After viewing the cosmos with 7×35 binoculars, I was quite impressed with the power of this model for the price. Where before I was looking AT star clusters like M39, the 20×80 made me feel like I was looking THROUGH the cluster! Great tool for my hobby-level of astronomy.

    I am very happy with the binocular I received. It feels and acts like a great quality high precision instrument. It was safely packed, delivered on time. The support team was very responsive. Thanks Oberwerk, will definitely buy more from you in the future.

    I had these for a few days. Viewed comet NEOWISE as the first night sky object. These are really nice and can’t wait to get them out to some dark sky. For the money they can’t be beat. The case is nice to protect them. They sat nicely on my camera tripod for the quick view of the comet and then Jupiter and Saturn. These will get a lot of use in the coming months. If you are on the fence about these get off and order your own. Enjoy

    It’s not just the stellar (pun intended) quality of the glass, and thus the views, but the light weight that make these so invaluable to me. I’ve had my 20×80 LW for a decade, and they’re still going strong; only needed a recollimation once in all that time. Easily the best viewing of any of my binos (smaller Nikon and 15×70 Celestron), and I’ll replace each of those with Oberwerk eventually.

    Moving from handheld 3 pound 15×70’s to handheld 4 pound 20×80’s was a breeze. Easy to lock-in the gems of the night sky with a significant gain in observing distant objects with the magnification increase and optical quality improvements. Great purchase.
