Northmere Holm 8x42 ED binoculars, with tripod adapter

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

This listing covers one configuration of the Northmere Holm 8x42 ED binoculars, defined by its package, optical coatings, armor color, and edition year. 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. Fully multi-coated optics treat every air-to-glass surface, which raises light transmission and image contrast.

Olive rubber armor offers the same protection as the black version in a different color. This is the 2025 edition, which added a firmer diopter lock so the setting holds when you pass the binoculars around. Before you add a mount or adapter later, check the compatibility notes for the thread and fitting that this binocular uses.
