Description

The Strider 32 mm is a five-element wide-field eyepiece with a 52-degree apparent field and a 2 in barrel. Its 30 mm field stop gives a wide true field at low power, and the eyepiece is built for telescopes with a 2 in focuser. Use it to locate targets and to frame large deep-sky objects, such as the Pleiades, in a single view.

A 32 mm eyepiece gives low magnification in most telescopes. It produces about 31x in a 1,000 mm refractor, about 38x in a 1,200 mm Dobsonian, and about 63x in a 2,000 mm Schmidt-Cassegrain. In the 1,200 mm telescope, the true field is about 1.4 degrees, enough to frame the full Moon with room around it. Low power also gives a bright image and a wide exit pupil under dark skies.

The five elements are arranged to keep stars sharp across most of the field in telescopes slower than about f/6. Faster Newtonians show some softening toward the edge of the field. All air-to-glass surfaces are fully multi-coated, which reduces ghost images from bright stars near the edge, and the barrel interior is blackened to reduce internal reflections.

With 20 mm of eye relief, the eyepiece suits observers who wear glasses when the fold-down rubber eyecup is lowered. Raise the eyecup to block stray light when the eye is close to the lens. The barrel is threaded for 2 in filters.

At about 480 g, the eyepiece is heavier than most 1.25 in designs. Check that the focuser and diagonal are rated for 2 in accessories, and tighten the focuser lock screw before observing so the eyepiece stays in place.

About this configuration

This listing covers one configuration of the Halden Strider 32 mm wide-field eyepiece, defined by its case, eyecup, finish, and edition year. The hard foam-lined case protects the eyepiece from knocks during travel and stacks neatly with other cases. A hard case keeps the eyepiece safe in a busy accessory box at a star party or an outreach event. A fold-down eyecup is simple and has no moving parts that can loosen in cold weather.

Titanium gray shows dust and fingerprints less than black, and it keeps a uniform look over time. This is the 2023 edition of the Strider line, the earliest version that is still listed in the catalog. Check the barrel size in the specifications against your focuser or star diagonal before you choose a configuration.
