Regal ED Flat Field Binoculars build on the success of Celestron’s customer-favorite Regal ED spotting scope line. With both ED objective lenses and flat field lenses, these binoculars provide sharp, expansive views and of a high degree of accurate color 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 color resolution, expansive fields of view for ease of locating fast moving objects, and 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 color 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 color. But not all ED binoculars are created equal. 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.
