    I have been an amateur astronomer for many years and have built my own telescopes including grinding the mirrors. I have also owned numerous binoculars over the years and actually do more binocular astronomy than telescope astronomy. Belonging to the local astronomy club, which includes many birders, I get to look through a wide assortment of binoculars.

    Understanding the worth of fine optics and justifying the price for near perfection, I was on the verge of purchasing a pair of Fujinon 10×50 FMTSX when I had the opportunity to look through a pair of Oberwerks and was blown away. After a couple of phone calls to Kevin Busarow of Oberwerk, who is as knowledgeable about binoculars as anyone I have ever known, I ordered a pair of Oberwerk 10×50 Ultras. These are simply the best binoculars I have ever looked through, even better than my immaculate, WWII Zeiss (Jena) 7x50s, which I inherited. The Oberwerks are no sharper than my Zeiss but the field of view is as wide if not slightly wider, which is pretty amazing since they have greater magnification. Of course, my Zeiss were state of the art 65 years ago.

    Shortly after I purchased the Oberwerks, I had the fortune to compare them with a pair of new Fujinon 10×50 FMTSXs. I spent the better part of an hour comparing the view of a radio antenna on top of an office building a couple miles away through both binoculars during the daytime–a very tough test for any binocular. The view through the Oberwerks was every bit as pleasing as the Fujinons. The view was tack sharp, alignment was dead on, field of view and eye relief were indistinguishable. Edge distortion was similar. I simply could not find anything inferior about the Oberwerks as compared to the Fujinons. The helical focusing eyepieces are as smooth as silk. The Oberwerks were slightly heavier but, to my way of thinking, this is a good thing as it translates into robustness and steadier holding. And on a tripod, it is a mute point. And, you should be using a tripod if you are doing astronomy.

    My next binoculars will be the 15×70 Ultras by Oberwerk to replace my 15×50 Celestron Skymasters. The Skymasters were good for the $90 I paid for them but I am now spoiled by the Ultras. I will also be ordering a tripod and parallelagram mount.

    Having used the Ultras for a while now, I have no regrets whatsoever by choosing them over the Fujinons.

    I recently attended NEAF for the first time and was extremely pleased to find out that I had won a pair of 10×50 Ultra binoculars that your company had donated as a raffle prize. I have four other pairs of binoculars and none have provided me with the visual experience that your binoculars have provided. The clarity of the optics, the sharpness of the images and the bright, wide and flat fields are amazing! I just wanted you to know that they have quickly become my favorite binoculars and I thank you for providing such a wonderful raffle prize. I hope to get many years of viewing pleasure with them. Thanks!

    The 10X50 Ultra’s are superb for stargazing!
    To begin with, I have 1st owned the 15X70 Ultra’s now for about a year and a half and am always stunned at the optical quality of this model. The extraordinary sharpness of the stars contrasted against such a strikingly dark background, still puts me in awe every time I pull them out of their beautifully crafted custom aluminum case. (Yes, I am a little enamored with these.) That said, I still would find myself sometimes wishing for that same level of quality, but in something a little bit more hand-holdable. My natural choice had the be the 15X70’s little brother, the 10X50 Ultras. And these binoculars have now become my new favorite “grab and go” binoc! These are simply amazing. Just as crisp an image with only a little loss in brigntness and resolution, but the tradeoff… The freedom to not have to set up a tripod, to just step outside without a moments hesitation, is so wonderful. There is something to be said about the “convenience factor”. I remember reading an article years ago in Sky and Telescope about a guy who bought a very high end but extremely bulky and heavy scope. It had amazing images but 9 times out of 10, he would grab his little 6″ Newtonian reflector and run out to observe instead! Convenience! Extremely comfortable to handhold, the 10X50 Ultras feel rock solid in your hands. I have tried some very expensive roof prism binocs which were almost 1/2 the weight. (Thinking this would be so much easier to hand-hold.) They had decent optics but the lighter weight and narrower profile actually made them harder to hold for stargazing. I think the broader shape of a porro prism itself lends towards a more comfortable gripping position and the additional weight is not at all deterrent. It literally helps stabilize the binoculars in your hands. Now, with that said, on Kevin’s recommendation, I did also grab Oberwerks 2000 Series Monopod with Grip-Action Ball Head, which is a fantastic addition, quick to set up, and it helps stabilize the 10X50 Ultra’s even more, but without the bulkier full tripod. But with or with out a tripod or monopod, these binocs stand completely on their own. They even look magnificent sitting out on my dresser. Like some sentient icon of the stars beckoning me to take them out and let them strut their stuff. You think I’m kidding? Set them out on your dresser and see if you don’t go out stargazing about twice as often as you used to! 🙂

    Ordered it on Saturday got it Wednesday , this is well built but no surprise I have 15×70 deluxe ,the optics are sharp I don’t see how you can get any better ,it makes it a pleasure to look threw . I decided to replace my B L 10×50 I am seeing double threw it it needs to be contaminated ,this is a very good company and if something happens to it they can fix it going to be extra careful I’ll guard it with my life ,and it’s light enough to hand hold ,but a mount makes a big difference ,I like to keep a 10×50 in my truck that’s easy to get to and this is perfect ,I am still in wow how sharp it is, I couldn’t decide on witch 10×50 to get ,back in the day I would just got all three ,but I decided to go with this one ,the individual eyepiece focusing is not a problem for me,one of my 25×100 has it I think I prefer it ,enough said I am going out to do some viewing, Rick from N H.
