Celestron – TrailSeeker ED 8×42 Binoculars Overview

What makes Celestron’s TrailSeeker ED 8×42 binoculars so special?

TrailSeeker ED is a binocular designed specifically for outdoor use. Due to its magnesium alloy construction, it is lightweight and corrosion-resistant. The fact that it is accessible by boat makes it incredibly appealing to people who like to travel by boat. Here, the optical tube is filled with nitrogen and is also O-ring sealed to make it waterproof as well as resistant to fogging in case of extreme temperature changes or bad environmental conditions.

Celestron has added tethered front and rear lens caps to this model to add an extra layer of protection as well. In this way, the binocular can react quickly to opportunities without having to worry about losing its caps. A harness system is also located in the binocular so, when you move through challenging terrain or trails, it won’t hang or sway. As a result, the weight will be distributed to your shoulders instead of your neck, so carrying it all day will be much more comfortable.

Features of the Celestron – TrailSeeker ED 8×42

Lens System and Optics

  • The binocular has an 8x magnification. To provide a comfortable viewing experience, the magnification is coupled with a wide exit pupil and a long eye relief.
  • The standard objective lens is 42mm. As a result, it provides bright and clear images regardless of lighting conditions.
  • Aside from the light, you also get an Extra-low Dispersion (ED) glass that reduces the overall chromatic and spherical aberrations to produce views with true color. There are no effects such as halos, distortion, or even diffraction in the images.
  • With the BAK4 prism system, you will get an incredibly crisp, as well as a very clean image.
  • An internal surface reflection can be boosted with dielectric prism coatings. The maximum light transmission is 99%. It means that the prism has a very small amount of diffraction. A clearer image, as well as incredible contrast, were made possible.
  • Phase-corrected coatings are also used on the lens system to reduce overall internal interference.
  • In addition to being multicoated, the lens maximizes the transmission of light, providing accurate colors from the view.
  • With a wide 65 degrees field of view, you minimize the distraction that takes place when you hold a high-powered optic. Distance-wise, the binocular offers a pretty wide field of view at 1000 yards of 426 feet.

Usability and Comfort

  • You get an eyecup that you can twist up and down with or without glasses.
  • The binocular can be mounted on a tripod and has an optional adapter for hands-free viewing as well.
