Are you ready for the next solar eclipse? On October 14th, an annular solar eclipse will be viewable from a swath from Oregon through Texas. The rest of the USA will experience a partial eclipse. Note that an annular eclipse means that the Moon is at or near its farthest point from Earth. Therefore it’s smaller, and won’t totally obscure the Sun- so you’ll need solar filters at all times to safely view it. Oberwerk carries Seymour solar filters, which are custom-fit for all Oberwerk binoculars (42mm and larger). Seymour Helios thin-film has a consistent yellow-orange solar image, with higher contrast than competitor’s filters. For binoculars capable of magnifications greater than 25x (our XL Series), we also offer Seymour Premium Glass filters, for highest-possible resolution. The filters snugly-fit over the objective-end of the binocular so the sunlight is safely-filtered before it enters the binocular. Most sizes are still in stock, but they’re selling out quickly!

Our friends at Binomania recently got their hands on two of our new SE (Special Edition) models- the 8×32 and 12×50. The following reviews are in Italian, but you can turn on closed captioning and select your language.

Neil English was so impressed with our new SE Series Porro prism binoculars that he wanted to check out one of our roof prism models. We sent the 8×42 Sport ED, here is his review.

NEAF (Northeast Astronomy Forum), held at Rockland Community College in Suffern, NY, is the world’s largest astronomy convention. Oberwerk normally exhibits there every year, but the event has been cancelled for the last 3 years due to Covid. It’s finally back on for the weekend of Apr. 15th. We’ll be there demoing every binocular in the Oberwerk product line, as well as our various tripods and mounts. We’re not bringing any inventory to sell, but we can relay orders to our office in Dayton, OH, and those will ship the following week (no sales tax, free shipping). We’ll be giving away our beloved Oberwerk pens, as well as Oberwerk eyepatches for telescope users- because telescopes are for one-eyed pirates 😉
Our booth location is 123-127, look for the banner below. Stop by and say hello!

There’s been a recent trend in the binocular industry to offer a “lifetime warranty” or “no-fault” warranty. Let’s think about that. What other products do you buy that come with that kind of warranty- cars, computers, televisions, cell phones, home appliances? Of course none of these come with lifetime warranties, it would be ridiculous to expect that! Why should binoculars be any different? Depending on how well you take care of them, they might last a couple years, or the rest of your life- that’s up to you. The implied message of the lifetime warranty is “our binoculars are so well made that they’ll last forever”. That’s nonsense of course. Speaking as somebody that’s been repairing binoculars for 24 years- no matter how well a binocular is made, it’s a precision instrument, and owners will find ways to break them. The question is, do you want to pay extra up front to cover the cost of an insurance plan, or would you rather pay the lowest-possible price for your binocular, take good care of it, and if you do happen to break it at some point- just pay the cost to repair it, or possibly replace it depending on how old it is, and perhaps upgrade to a new and improved model?

The first step in analyzing a warranty is to read the fine-print and know what’s covered and what’s not covered. Some manufacturers offer a ridiculously-long warranty period- 10 years, 20 years, even “lifetime”- but then exclude anything that’s not a “manufacturer’s defect”. The truth is “manufacturer’s defects” will usually be obvious on day one, and will certainly show up within the first year of usage. So it doesn’t matter how long the warranty period is, if it’s only covering manufacturer’s defects, it’s not likely to cover anything after the first year. After the first year, there are only a few things that can go wrong-

1. The number one answer- the binocular was damaged from a hard drop
2. The binocular was left outdoors 24/7 and now there’s internal fogging or water intrusion
3. The dog chewed-up the rubber parts

If the warranty does not exclude accidents or abuse of product, then you have to ask- who’s really paying for that cost? Is the manufacturer eating it, just because they love their customers? Or did you pay for an insurance policy in the price of the binocular when you bought it? If you’re a manufacturer, and your cost to build a binocular is 30% of the selling price, you could probably afford to replace a binocular for any reason- and still be profitable. If your cost to build is more than 50%, replacing a binocular will make that sale a loss. Oberwerk’s cost to manufacture averages well above 50% selling cost, with higher-end products above 60%. With our thin margins, Oberwerk products can only only sold direct, and not through resellers. We do love our customers- so we offer to them great products at lowest-possible prices. Because of that, we simply can’t afford to replace binoculars that don’t have manufacturer’s defects. What we do is thoroughly inspect each and every binocular, to be sure it doesn’t ship with a defect, and to be sure the alignment is as perfect as possible. We then offer a 15-day satisfaction guarantee, where we’ll replace or exchange for any reason, and completely at our cost- or we’ll simply accept a return. We include a 2-year or 3-year warranty (depending on product) to cover any possible defects that don’t show up right away, which is probably more generous than the warranties on most other products that you buy. Beyond that, if something goes wrong- sorry, you broke it. We’ll take care of it, but we’ll charge a reasonable price to do so. We could change our warranty to a “lifetime limited warranty”- but that would just be a marketing gimmick as there will be no manufacturer’s defects discovered years after the purchase. You’d still pay for breaking it. Alternatively, we could mark up binoculars by an extra 30-50%, and then cover accidents like some manufacturers do- but do you really want to pay a higher price to cover the costs for customers that don’t take care of their things? Or would you rather pay a lower price, knowing that if you break it, you’ll need to cover that cost? If you’re the type of person that buys extended warranties, then perhaps a “no-fault unlimited warranty” is for you- because you’re paying for an extended warranty in the price of the binocular. If you appreciate a good value, and you take care of your possessions, then you might want to avoid paying up-front for “unlimited no-fault warranties”.

Astronomy Magazine has awarded the Oberwerk BT-127XL-SD as a “2022 Star Product”. “Welcome to the 12th annual Star Products awards. This year, as in the past, we scoured the market in search of the 35 best new and unique astro products. Our winners this year, presented in no particular order, offer a mix for newbie and veteran hobbyists alike. #19. Oberwerk recently introduced the BT-127XL-SD, the largest member of its binocular telescope family. The glossy white binoscope pairs two identical 127mm apochromatic refractors. Each has a fully-coated three element objective lens made of FCD100 and FK-61 glass to eliminate false color. Despite the size of the large objective lenses and prism assemblies, the BT-127XL-SD weighs only 24.5 lbs (11 kg). It comes with two 14mm eyepieces and a heavy-duty case with wheels for easy transport. A mount is sold separately.”

If you don’t wear glasses, eyepiece eye relief is usually not a concern. Even if you do need corrective lenses for farsightedness or nearsightedness, our binoculars usually have enough range in their focusers to compensate for your correction, allowing you to observe with glasses off. But if your glasses are correcting for astigmatism, you’ll probably get sharper views by keeping your glasses on- in which case eye relief will be an important specification. If it’s too short, you won’t be able to see the entire field of view when wearing glasses. There’s always been a difference between binocular manufacturer’s eye relief specification and actual usable eye relief. Whether it’s space taken up by whatever style eyecup is utilized, or a recess from the top of the eyepiece to the actual lens, manufacturer’s eye relief specifications have always been exaggerated to some degree- until now. Introducing ROAMER (Ridiculously Over-engineered Accurate Measure of Eye Relief), which Oberwerk will now use to provide precise usable eye relief specifications for every Oberwerk binocular. Note that these new specifications will make Oberwerk binoculars appear to have less eye relief than binoculars from other brands. But that’s not the case- our eyepieces are no worse than others in this regard, and they’re often better- but at least you’ll have accurate information from now on.
