BT-70XL-ED Binocular Telescope

hot2009(color)SmallThe largest members of the Oberwerk Ultra Series have huge 110mm objective lenses, with very large stepped prisms to match. These objectives gather a tremendous amount of light, resulting in the brightest and highest-quality high-power views available from any sub-$1000 binocular on the market. Very rugged construction with precise individual focusers. Of course they are fully broadband multi-coated, waterproof, and nitrogen charged. Includes our new-for-2017 Oberwerk Heavy-Duty aluminum-frame case. Available in your choice of either 20x or 28x. Note that the 28x model is a long-range binocular, the minimum focus distance 200 meters. If you need to view targets closer than that, choose the 20x model, which will focus down to 30 meters.

asy-2010starproduct_logo100wThese 110mm binoculars are 21″ long and weigh 16 lbs., so a sturdy tripod is required. We recommend either the Oberwerk 5000 Series Tripod/Head (as shown) or the Oberwerk TR3 Wood Tripod with 5000 Head.

    Hi there folks!
    I have had both my Oberwerk Ultra (28×110), and my Deluxe (25×100) for some time now. I have enjoyed both of them! I have the perfect setup for both when it comes to star gazing. I have been using both of them so much, my other scopes have been on the back burner for more than two months!
    The views I have been getting are nothing but fantastic. The eye relief is great for me, and the stars are very beautiful. I really enjoy looking at globular, and open star clusters the most.
    I have used both of them at star parties, and many of the people there are amazed with the views. I have even turned a couple of astro imaging friends back to exploring with bino astronomy. One of them will be leaving his imaging equipment at home for the second time in a row, and bring his binoculars.
    Thanks again for these awesome binos! I am enjoying them very much!

    My first experience with the Oberwerk’s Ultra 28×110 started out less than perfect. The prisms had been jostled during shipping. I contacted the company and they promptly sent me out a new binocular. Very friendly and probably the best customer service experience I’ve ever had. Needless to say, that brief early frustration is completely gone and I have nothing but praise for the company and their product.

    The Ultra 28×110 itself is amazing. The image clarity and ease of use is beyond what I expected by a large margin. I’ve used it mainly for distance viewing from a bluff overlooking the Pacific Ocean. The detail visible on distant ships is sharp and clear and I can see markings on some of the whales passing by at a distance of nearly a mile. So far I have’t had a clear night to do any star gazing, but with the Oberwerk’s 5000 series tripod, it should be great.

    Thanks a million!

    I recieved my 28×110 last week. WOW! These are big boys! Well made as well. It’s a lot of dough to spend on a pair of binoculars, however, once you have them you’ll be happy you did! Just keep in mind, they are heavy boys! For me they work well. I look for things in the sky, and BTW, they are up there! I used a pair of 26×70 Russian bino’s and was shocked to see things moving around. When it’s not so $#@%$ cold out I will continue my search for the hot rods of the sky! It a blast! These will be awesome!!

    I never write reviews but have to make an exception here. My Ultra Series 28x110m binoculars and TR3-P wood tripod arrived today and I was floored. The quality was well-beyond my expectations – what a set up. If I paid twice as much I would still be happy. I live on the Atlantic and have elevation so I am able to scope long distances. The clarity and eye relief are perfect, not to mention the amazing powerful optics. I’m clearly seeing boats and identifying them that I can’t even see with the naked eye. Anyone considering purchasing this product – go for it – the quality of the products is outstanding! You will not be disappointed. Fantastic purchase.

    Hi all. I recently received my pair of 20×110 binoculars and they are awesome so far. Perfect alignment handheld and on a parallelogram unimount. Yes I did say handheld LOL. They do weigh 16 pounds, glad I have strong shoulders. I chose the 20x version because I wanted a wider and brighter view of the sky. I’ve viewed through 25×150 Fujinon binoculars out at TSP (Texas Star Party) and I loved how bright the sky and objects were. I had my Oberwerk 25×100’s at the time and the same objects were 4x darker (100mm vs 150mm). The point I’m making here is that the 20×110’s give me a brighter view like I remember from the Fujinons did. These 20×110’s give a 37% gain in light grasp over the 25×100’s, which I still have. This was calculated by Kevin at Oberwerk and that 37% gain pushed me to buy them. I took them out to a dark location to test them, wow! Bright objects and detailed views. M51, M81/2, Omega Centauri, to name a few were excellent. I love these! I chose the binoculars instead of buying a small telescope. I highly recommend the 20x110mm because of the excellent wide field views.
