The new Oberwerk 25x100mm IF (individual focusers) is ideal for serious binocular astronomy on a budget. The precision individual focusers are sealed, so the dry nitrogen stays in, and moisture stays out. Features full broadband multi-coating (all air-to-glass surfaces, including prisms), all-metal contruction with rubber armor, braced and hinged objective tubes, built-in mount- at a price that's almost too good to be true. This binocular has a 2.5° field of view, with very good sharpness across the entire field. The eyepieces have fold-down eyecups that work well with glasses (eye relief is a comfortable 18mm). Includes objective covers, ocular caps, and our deluxe aluminum case!
