Celestron Regal 8x42 ED Flat Field Binoculars

The Celestron Regal 8x42 ED Flat Field Binoculars (product 47032159469875) pair 8x magnification with a 42mm objective lens. That gives you a 5.25mm exit pupil and a wide 140m field of view at 1000m genuinely useful for tracking fast-moving birds or wildlife. The 4.9-foot close focus distance makes these exceptional for butterflies, plants and nearby subjects.

The objective lenses use ED (Extra-Low Dispersion) glass which virtually eliminates chromatic aberration that colour fringing you see on cheaper binoculars. Fully multi-coated optics across all air-to-glass surfaces maximise light transmission. BaK-4 prisms with phase coatings push more light through to your eye. The result is sharp, true-to-life colour with strong contrast.

The magnesium alloy body keeps weight down to 768g without sacrificing strength. Fully waterproof and nitrogen-filled to prevent internal fogging. Durable metal twist-up eyecups with multiple click stops suit both eyeglass and non-eyeglass wearers. The 22.5mm eye relief is generous. Flat field technology delivers edge-to-edge clarity.

These are tripod-adaptable for digiscoping. The kit includes a hard shell case, padded strap, cross-body harness and lens covers. Backed by a lifetime manufacturer warranty. Built for birders who want performance-level glass.

The 8x42 pairing gives a 5.25mm exit pupil solid for low light use. ED glass reduces dispersion so colours stay accurate with no fringing at high contrast edges. Fully multi-coated optics coat every air-to-glass surface with multiple anti-reflectivity layers pushing maximum light to your eye. BaK-4 prisms with phase coatings maintain contrast and sharpness through the optical path. Flat field lenses correct field curvature so the image stays sharp right to the edges. The 140m field of view at 1000m is wide enough to track fast-moving subjects with ease.

The chassis is magnesium alloy strong and light at 768g. The objective lenses use ED extra-low dispersion glass. Prisms are BaK-4 glass with phase coatings applied. All optical surfaces carry multiple layers of anti-reflectivity coatings. The eyecups are durable metal with a twist-up mechanism. The body is fully sealed and nitrogen-filled.

Use a blower brush before wiping lenses with a clean microfibre cloth. Store in the hard shell case when not in use. Keep the neck strap attached to avoid drops. Store in a dry place. Check the hinge tension periodically. The lifetime warranty depends on normal careful use avoid impact and never use abrasive materials on the lenses.
