Alpen Chisos 8x42 ED BinocularsTrying to ID warblers in dense canopy means fighting dim light, cluttered backgrounds, and color fringing that turns subtle plumage differences into guesswork. The Alpen Chisos 8x42 cuts through that with ED glass and PXA phase coated prisms that deliver true color and sharp detail across a wide 368 foot field of view plus a 6. 5 foot close focus that keeps feeder birds and butterflies in play.

Trying to ID warblers in dense canopy means fighting dim light, cluttered backgrounds, and color fringing that turns subtle plumage differences into guesswork. The Alpen Chisos 8x42 cuts through that with ED glass and PXA phase-coated prisms that deliver true color and sharp detail across a wide 368-foot field of view — plus a 6.5-foot close focus that keeps feeder birds and butterflies in play.

Key Features

• ED Glass — Extra-low dispersion elements eliminate chromatic aberration on high-contrast edges, keeping plumage colors true and fine detail sharp even against bright sky.
• PXA Phase-Coated BaK-4 Roof Prisms — Phase correction preserves resolution and contrast edge-to-edge for confident ID work across the full field.
• Fully Multi-Coated Optics — Every air-to-glass surface treated for maximum light transmission and minimal glare under overcast skies and forest canopy.
• 368ft Field of View at 1,000 yds — Wide enough to find and track fast-moving birds without constant panning.
• 6.5-Foot Close Focus — Tight enough for feeder birds, butterflies, and wildflowers at arm's length.
• Lightweight Magnesium Housing — Durable yet comfortable for all-day carry with textured grip panels for secure handling.
• Waterproof & Nitrogen-Filled — Sealed against rain and humidity, internally fog-proof through rapid temperature swings.
• 18mm Eye Relief with Twist-Up Eyecups — Comfortable full-field viewing for glasses wearers across extended sessions.

Ideal For

• Birders who need color-accurate, high-resolution views to distinguish subtle plumage differences in canopy, at forest edges, and during dawn/dusk activity peaks.
• Close-focus enthusiasts who observe feeders, insects, and wildflowers at short range — 6.5 feet is tighter than most competitors.
• Hikers and nature observers who want ED glass quality in a lightweight, weatherproof package for all-day trail use.
• Glasses wearers who need generous eye relief without sacrificing field of view.
• Mid-range upgraders stepping up from non-ED optics and wanting a meaningful improvement in color fidelity and edge sharpness.
