Description
The Fjord 8x42 ED binoculars combine 8x magnification with 42 mm objectives and extra-low-dispersion glass in the objective lenses. The 8x power gives an exit pupil of 5.25 mm, which suits most observers under dark skies, and the 7.0-degree true field produces an apparent field of 56 degrees. That view is wide enough to frame the Pleiades, the Double Cluster in Perseus, and large star fields along the Milky Way in Cygnus.
The ED elements reduce colour fringing around bright stars such as Vega, Capella, and Sirius, and the edge of the Moon appears more defined than in standard-glass models at the same power. The BaK-4 roof prisms carry phase-correction coatings, and all air-to-glass surfaces are multi-coated to keep transmission high. The 42 mm objectives gather less light than 50 mm designs, so fainter stars are slightly harder to see, but the 5.25 mm exit pupil matches the dilated pupils of many observers and keeps the sky background dark.
The 18 mm eye relief lets you keep your glasses on and still see the full field. The central focus wheel and right-eye diopter adjust with a smooth, low-friction action, and the twist-up eyecups lock at two positions. At 880 g, these binoculars are practical for hand-held sessions of up to half an hour. For longer sessions, rest your elbows on a wall or a car roof, or use a tripod adapter to keep the view steady.
Start with the Moon a few days after new, and note how the crater edges look along the terminator. Then sweep Cygnus, and return to the Double Cluster on a darker night to compare. Keep the objective caps on when the binoculars are not in use, and wipe the lens surfaces with the supplied cloth rather than a dry tissue.
About this configuration
All configurations of the Northmere Fjord 8x42 ED binoculars share the same magnification and objective size; the options below change the package and finish. The included tripod adapter lets you fix the binoculars to a photo tripod for steadier, more relaxed views. With the adapter on a tripod, hand shake disappears, which makes faint stars and close double stars easier to see. ED glass reduces the color fringing that otherwise appears around bright objects such as the Moon and Venus.
The olive armor has the same grip pattern and thickness as the other colors in the Fjord line. The 2023 edition uses the same prisms and objectives as later years, with small differences in the eyecups. The magnification, field, and exit pupil figures in the specifications table apply to every configuration of the Fjord line.
