The 15x56 ED Ultra Binoculars from Oberwerk are considered mid-sized, but there's nothing "mid" about their optical features. They feature fully broadband multicoated, extra-low dispersion FK-61 lenses and BAK4 prisms, with field flatteners for edge-to-edge sharpness. The big 56mm objective lenses welcome light for a bright image, and the 15x magnification will show you far-off terrestrial details or even stargazing targets like the surface of the moon.
Included is an adapter for a tripod with a 1/4"-20 stud. The eyepieces can be individually focused for precise adjustment. The 15x56 ED Ultra's lightweight magnesium alloy housing is nitrogen-filled for fog and waterproof performance. The chassis is wrapped in gray rubber armoring for slip and shock resistance as well as a comfortable grip.
