Come see us at NEAF 2019 (NorthEast Astronomy Forum), Apr. 6th & 7th, at Rockland Community College in Suffern, NY. NEAF is the world’s largest astronomy & space expo! In past years, our booth has been pretty cramped with all the tripods we need to bring. But this year, we expanded our exhibit space to 30′, so we can spread out and give visitors plenty of room to try out our new XL Series binocular telescopes mounted on our TR3 hardwood tripods, as well as the rest of the Oberwerk product line. We’ll also be showing our all-new TR3-matching maple parallelogram mount- the Oberwerk PM1!

SPACE.COM went on a quest to discover the best all-around binocular for astronomy, nature, sports and travel. It’s a lengthy article, but concludes with-
“No matter how much — or how little — you have to spend, it makes sense to have one “grab-and-go” set of binoculars that you can trust to bring all the world’s detail in closer; night or day, indoors or out. With their compact size, chunky-but-lightweight feel, superb clarity, lack of color distortion and precise focus, we believe that Oberwerks’ 8×42 ED is the one binocular to have if you can have only one.”
We couldn’t agree more. Here’s the link-
Best All-Around Binoculars for Astronomy, Nature, Sports and Travel

Last month, the popular Italian website binomania.it interviewed Oberwerk’s Kevin Busarow about the new XL Series binocular telescopes. This month, Binomania publishes their first review of the BT-100XL-ED, comparing it to the finest binoculars on the market. Note that it’s in Italian, but there is a Translate option on the right side of the webpage. The consensus? “In summary- I end this review confirming that the Oberwerk BT-100XL-ED is a quality product, has optics that rival the best (and more expensive) competition, is compact, lightweight, and perfectly adapted to terrestrial observations as well as those astronomical.” We couldn’t agree more!

In 2013, Oberwerk’s Kevin Busarow was trained in “Tail of the Arc” binocular collimation (alignment) on a Navy Mark V collimator by retired Navy Opticalman Cory Suddarth, of Suddarth Optical Repair. Shortly after returning from training in Oklahoma, Kevin built a working collimator from a surplus spy plane camera lens. The other necessary component- an auxiliary telescope- was supplied by Cory, with an extra-tall rhomboid prism for getting a direct view of the collimator image over the top of the larger binoculars that Oberwerk typically sells.
In August of 2018, when an ultra-rare genuine Navy Mark V collimator was put on the market by an optics collector in San Diego, Cory notified Kevin- and he jumped on it! With its massive 5-foot-long iron rail and solid copper housing, it was a beauty! Rather than risk trying to ship such a large, heavy, delicate, and irreplaceable piece of equipment, Kevin bought a one-way ticket to San Diego, rented a station wagon, and drove it back to Dayton, Ohio. Oberwerk has always been proud to say we’re the only binocular retailer on the planet (that we know of) with an in-house collimator- and now we have two at our disposal!

The odds are you had not heard of Oberwerk before you found our website. If so, you’ll probably be quite surprised to learn that for the last two decades, Oberwerk is the world’s leading supplier of high-power binoculars, outselling all other brands- combined! How can this be? Let’s start by defining “high-power”. There are a number of binocular brands that offer models that have as much as 25x magnification. But there aren’t many that operate at 40x (or higher). Let’s also immediately eliminate all (yes, all) “zoom” binoculars from the mix, as none of them are high-quality optical instruments. “But doesn’t the Spion 20-140×70 ‘Military Zoom’ binocular operate at 140x”? Sorry, that’s marketing hype- it’s a plastic POS (piece of crap), unusable at 140x, and overpriced even at $139. By the way, no military has ever deployed any zoom binocular, from any manufacturer- and for good reason. The lowest-price high-power binocular on market is the small but mighty $1595 Oberwerk BT-70XL-ED, capable of up to 56x magnification.
For long-range observation, the world’s militaries have deployed thousands of Oberwerk 25/40×100 Long-Range Observation binoculars, which have huge 100mm (4″) triplet objectives and built-in 25x and 40x eyepieces on rotating turrets. Amateur astronomers around the world have made our Binocular Telescopes the most popular choices for serious binocular astronomy. For the home-with-a-view, the ultimate instrument to enhance a great view has been the 25/40×100. But in 2018, Oberwerk announced the revolutionary XL Series binocular telescopes. Three years in development, the XL Series, with ED (or SD) objectives, 45-degree viewing, 1.25″ focusers, and ultra-light magnesium-alloy construction, are simply the finest binocular telescopes on the market, regardless of price. The XL binocular telescopes have effectively made the 25/40×100 somewhat obsolete, and the world’s militaries, as well as the home-with-a-view customer, are switching to the optically-superior XL models.
Over the years, Oberwerk has quietly sold over 7500 25/40×100 Long-Range Observation binoculars and binocular telescopes. That’s more high-power binoculars than all the binocular brands you’ve heard of have sold- combined! Even we think that’s pretty remarkable!
With our new XL Series, which start as low as $1595, not only will Oberwerk continue to dominate the high-power binocular market, we’ll no longer be the brand you never heard of.

I was recently asked “what’s different about your brand- what sets Oberwerk apart from the competition?” Well, there are a number of unique and important things that make us different- but just one that I want to talk about right now.
If you’re considering buying a binocular, ours or another brand, you probably have some questions- especially so if you’re looking at one of our Long-Range Observation binoculars or our Binocular Telescopes. The fact is I spend much of my day on the phone answering questions and answering questions by email. The first thing I do in the morning is respond to the email questions that came in the previous night. When I think a question/answer might be interesting or informative to others, I’ll post them on our Email Questions/Answers Archive. I wear a wireless headset so I can take customer calls while I’m checking/testing binoculars that are to be shipped that day, or building our TR3 hardwood tripods. I’ve heard countless times “you’re the only company I can contact and get thoughtful and knowledgeable answers to my questions.”
So when I was recently asked “what makes us different”, it struck me that there really is no other binocular retailer I can think of that you can call and speak instantly with, or email and get a timely reply from, someone that is truly knowledgeable about their products, as well as the competition’s. Someone that’s lived and breathed binoculars for the last twenty years. Someone that’s not a salesperson or an order-taker. But your business is selling binoculars- right? True, but I don’t consider myself a “sales type” at all, I’ve never read a book on how to close a sale. But what I do pretty well is answer customer’s questions, explaining technical things in a way people can understand. I believe that our products are such a unique value, that as long as I can impart enough knowledge to a customer, they’ll come to that conclusion on their own- without any arm-twisting on my part. Sometimes our product isn’t the best solution, and I’ll be the first to say so. Sometimes I have to set realistic expectations- “no, you can’t read a license plate 3 miles away“, “yes, you can see the rings of Saturn, but it’s still a very small object in the field of view“, because 1) nobody likes dealing with returns and 2) we want everyone to be thrilled with their purchase. They’ll tell their friends and relatives, and they’ll want one too, and so on- until everyone on the planet has heard of Oberwerk.
