Oberwerk high-quality 60mm binoculars- at a 50mm price! That extra 10mm doesn't sound like very much- but 60mm objectives gather 30% more light than 50mm models (surface area = pi*r2). With that much extra light-gathering power these are ideal for a low-cost entry into binocular astronomy. They are also excellent for birding nautical applications and surveillance. Not only do you get big 60mm objectives- you get the same highest-quality BAK4 prisms that are found in much more expensive models. These are available in your choice of either 9x 12x 15x or 20x magnification. All air-to-glass surfaces are fully coated to decrease light loss due to scattering and reflections. Objectives have highest-quality green/purple broadband multi-coatings typically only found on binoculars with much higher price tags. All Oberwerk binoculars have rugged rubber-armored metal bodies all-glass lenses right ocular diopter adjustment brass 1/4-20 tripod adapter threading case caps and strap.
