Northmere Holm 8x42 ED binoculars, with photo tripod

Specifications

Description

The Holm 8x42 ED binoculars pair 42 mm objectives with extra-low-dispersion glass elements that reduce colour fringing around bright stars and the Moon. The 8x magnification gives an exit pupil of 5.3 mm, which suits most observers under moderately dark skies. The 7.4-degree true field produces an apparent field of about 59 degrees, enough to fit the Double Cluster in Perseus, the Pleiades, and a long stretch of the Milky Way in Cygnus into a single view.

Brace your elbows against your chest or rest the binoculars on a fence post or a car roof to hold the view steady. Use the central focus wheel to set sharpness on a distant star, then turn the right-eye diopter until that star is equally sharp with your right eye. The 17 mm eye relief lets you keep eyeglasses on and still see the full field, and the twist-up eyecups set the eye distance for both glasses and bare eyes. The phase-corrected roof prisms and multi-coated lenses keep star images round and contrast high across the field.

At 880 g, the Holm 8x42 is comfortable for hand-held sessions of an hour or more, and a parallelogram mount or tripod adapter reduces fatigue on longer sweeps. The fully sealed body is purged with nitrogen and resists fogging, so the binoculars can move from a warm room into cold night air without internal condensation. The 2.0 m close focus lets you view nearby foliage or a dew-covered garden, and the wide field helps when you follow a satellite pass or a comet across the sky. Observers whose maximum pupil is 5 mm or less may find that a higher-magnification binocular shows more detail under the same sky.

About this configuration

The Northmere Holm 8x42 ED binoculars comes in several configurations, and the notes below explain what this particular combination includes. This package adds a photo tripod and an adapter, so you can hold the binoculars steady without further purchases. A tripod works well for objects at low and medium altitude, though viewing near the zenith becomes awkward on one. Fully multi-coated optics treat every air-to-glass surface, which raises light transmission and image contrast.

Desert tan armor stays cooler in direct sunlight, which helps during daytime use before an evening session. The optics in the 2024 edition match the other years; the changes concern handling details only. The magnification, field, and exit pupil figures in the specifications table apply to every configuration of the Holm line.
