About this product

Model:  cel_regal_8x42_ed
Part Number:  71390-CGL

With ED objective lenses and flat field optics, these Regal ED Flat Field binoculars provide sharp, expansive views and highly accurate colour resolution.

As Celestron’s new premiere line of performance-level field binoculars, the Regal ED Flat Field Binoculars are designed with the most selective of all binocular users in mind: birders. From their vivid, true-to-life colour resolution, expansive fields of view for ease of locating fast-moving objects, and 1.5m (4.9 foot) close focus distance to get an even closer look when a subject suddenly pops out of the bushes and right on the trail in front of you, the Regal ED binoculars provide everything needed for the most selective of binocular users – which ensures that they’re up to the challenge across a wide range of other activities.

ED Glass Objective Lenses

Extra-low dispersion (ED) glass virtually eliminates chromatic aberration, also known as colour fringing, a distracting visual effect produced when different wavelengths of light disperse while transiting optical lenses. By reducing dispersion, the Regal ED binoculars provide images with outstanding, true-to-life colour. However, not all ED binoculars are created equal. Celestron’s high-quality ED glass objective lenses deliver brighter, sharper images than non-ED binoculars. The difference is especially apparent in low-light conditions, such as at dawn or dusk.

Flat Field Technology

In addition to using ED glass, the Regal features flat field optical technology that counter-balances the normal visual field curvature convex lenses naturally show, delivering an expansive linear image all the way to the edges of the field of view.

Coatings and Prisms

Regal ED features fully multi-coated optics. A binocular can be considered “fully multi-coated” when all air-to-glass surfaces are coated with multiple layers of anti-reflectivity coatings so that the maximum amount of light passes through the glass to the eye.

The prisms inside Regal ED are made of high-quality BaK-4 glass with phase coatings applied to reflect more light off their internal faces.

The fully multi-coated lenses and BaK-4 prisms maximise light transmission to deliver remarkably bright, highly detailed views. The ED objective lenses further enhance these features, especially in low-light conditions.

The Body

The well-balanced, ergonomic industrial design magnesium alloy body protects your Regal ED binoculars from damage without weighing you down. Viewing through Regal ED is comfortable for both eyeglass and non-eyeglass wearers, thanks to the durable metal twist-up eyecups. You can easily find the best position using the clearly defined click-stops. Moreover, the binocular is fully waterproof and filled with dry nitrogen gas to prevent internal fogging of lenses. Regal ED can stand up to even the most challenging outdoor conditions.

Perfect for a Variety of Uses

Regal ED 8x42mm features a close focus of just 4.9 feet, making it perfect for viewing birds, butterflies, plants, or other nearby subjects. The 8x42 model offers a wide field of view, making it easier to follow subjects as they move.

Ways to Observe

You can carry your Regal ED with the padded strap or on the cross-body carry harness for additional comfort. It’s also tripod-adaptable, so you can mount it on any standard photographic tripod for extended viewing or digiscoping (photography through the eyepiece). A tripod adapter is sold separately. The included one-piece eyepiece cover keeps rain, dust, and other substances off your eyepiece lenses in the field and protects them while in storage, while the tetherable objective covers provide additional protection for the Regal’s all-important objective ED lenses.  The binocular includes a premium hardshell case for secure storage and transport.

Solar Warning
  • Never look directly at the Sun with the naked eye or with this optic. Permanent and irreversible eye damage may result.
  • Never use your optic to project an image of the Sun onto any surface. Internal heat build-up can damage the optic and any accessories attached to it.
  • Never leave your optic unsupervised. Make sure an adult who is familiar with the correct operating procedures is with your optic at all times, especially when children are present.
