ED Glass objective lenses

Extra-Low Dispersion (ED) glass virtually eliminates chromatic aberration
Also known as color fringing, this distracting visual effect is 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 color
Celestron’s high-quality ED glass objective lenses deliver visibly brighter, sharper images compared to non-ED binoculars
The difference is especially apparent in low light conditions, such as at dawn or dusk

Flat Field technology

Counter-balances the normal visual field curvature convex lenses naturally show
Delivers an expansive linear image all the way to the edges of the field of view

Multi-coated optics

Fully multi-coated optics; all air-to-glass surfaces are coated with multiple layers of anti-reflectivity coatings
Prisms inside are made of high-quality BaK-4 glass with phase coatings
More light is reflected off the prisms' internal faces and passes through to the eye
Taken together, fully multi-coated lenses and BaK-4 prisms maximize light transmission for remarkably bright, highly detailed images
ED objective lenses further enhance these features, especially in low light conditions

Durable housing

Well-balanced, ergonomic industrial design magnesium alloy body protects your binoculars from damage without weighing you down
Durable metal twist-up eyecups makes viewing comfortable for both eyeglass wearers and non-eyeglass wearers
Twist through multiple click stops to find the position that works best for you
Fully waterproof and filled with dry nitrogen gas to prevent internal fogging of lenses

Variety of uses

Close focus of just 4.9' is perfect for viewing birds, butterflies, plants or nearby subjects
Wide field of view allows you to easily follow subjects as they move at a distance, with less need to move the binoculars

Ways to observe

Padded strap and cross-body carry harness included for comfort and to keep binoculars at the ready
Mount on any standard photographic monopod or tripod for extended viewing or digiscoping (tripod adapter sold separately)
