Designed as your go-to multipurpose outdoor optic, the Celestron 8x42 Regal ED Binocular features a suite of technologies and design features that will make it an essential part of your kit whether you're hunting, birding, or hiking.

Anti-reflection fully multicoated high-performance extra-low dispersion glass lenses with integrated field flatteners deliver crisp, true-color images of breathtaking landscapes and vistas free from distortion. Phase-corrected and dielectric-coated BAK4 roof prisms maximize light transmission through the prism system, limiting internal diffraction and interference and improving image resolution and contrast. The combination of 8x magnification and 42mm objectives help to produce a wide exit pupil and an exceptionally-long eye relief that virtually eliminates eye strain to greatly improve your glassing experience. When you put all these optical features together, you are presented with crisp and sharp high-contrast wide angle views with accurate color across the entire visible spectrum with limited distortion, especially at the edges.

Complementing its optical performance is a lightweight magnesium housing that is nitrogen filled and O-ring sealed to make it waterproof and resistant to internal fogging when you move through extreme changes in temperature or environmental conditions. The body features an ergonomic design with rubber armor and strategically placed texture that offers a secure hold and a pleasant handling experience, with the large center focusing knob providing smooth adjustments. To help you with focusing and correcting for dioptric differences, the focus knob and the diopter ring are knurled and can be easily adjusted even when wearing gloves. Ideal for fast glassing on the go, the Regal ED comes with tethered caps that won't get lost when you're out and about and a shoulder harness that eliminates strain on your neck and prevents it from swaying and swinging if you need to climb over rough and rocky terrain.
