Celestron TrailSeeker ED 8x42 Binoculars have a wealth of features rarely found at this price level. Among these are Extra-low Dispersion (ED) for reducing chromatic aberration, accurate colors, and improved resolution; fully multi-coated lenses for increased light transmission and better color response; and phase and dielectric coatings on BaK-4 prisms for improved light transmission. Close focus is 6.5', and field of view is a quite wide 426' at 1,000 yds. The TrailSeeker EDs are waterproof and nitrogen purged for use in adverse conditions. All this is packed into a 23.5oz package.

Chromatic aberration occurs because when light passes through an objective lens, the edges act like a triangular prism, breaking light into its spectral components so each color focuses at different distances from the eyepiece. This forces your eyes and brain to try to merge the colors, resulting in eye fatigue. ED glass narrows the amount that the colors spread out, bringing their focal points closer together, as shown below.
