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

All configurations of the Northmere Holm 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. Multi-coated optics reduce reflections at the main glass surfaces while keeping the price of this binocular low.

The black armor is the standard finish of the Holm line and matches its black lens caps. This is the 2023 edition of the Holm line, the earliest version that is still listed in the catalog. Compare the exit pupil in the specifications with your sky conditions and your age, since both affect how bright the view looks.
