Besides making night sky observation much more comfortable, a parallelogram mount gives a big range of eyepiece height without adjusting the tripod- and without loss of target (ideal for sharing the view with kids). For almost 20 years, the Universal Astronomics Unimount was the finest parallelogram-type mount on the market, and we sold a ton of them! Unfortunately UA is no longer in business, so we offer the next-best thing- a Farpoint copy of the Unimount called the UBM (Universal Binocular Mount). Like the Unimount, they are 100% made in the USA. Our UBM’s also come with a normally-optional swing-hinge, at the head- at a price still well below the basic Unimount. Note that while the Farpoint UBM is sold by several other dealers, only Oberwerk includes the $50 swing hinge– which is what gives the mount 5 degrees of motion, and is necessary in our opinion. Keep this in mind when comparing prices. Even with all those pivot points, there is virtually zero slop or backlash. While observing the night sky, you’ll feel like the mount is not even there. Because all axis’ are in perfect balance, the binocular simply “floats”, while you effortlessly point it in any direction. For the ultimate in comfort, try it with a reclining lawn chair. Comes with two 5 lb. counterweights, and will easily handle binoculars as large as the Oberwerk 25×100 Deluxe. Bottom-mount binoculars attach directly to the included dovetail base. For binoculars that have a tripod adapter socket on the front of the body, order the Oberwerk Heavy-Duty L Adapter or the Farpoint FAR-sight. The UBM does not include a tripod. For binoculars less than 10 lbs. we recommend the Oberwerk 5000 tripod, available without the 5000 head for just $169.95. For 10 lb. binoculars, the Oberwerk TR3 wood tripod is recommended.
