Celestron Trailseeker 10x42 ED

The 10x42 TrailSeeker ED binocular provides high-level outdoor performance—a perfect choice for avid birders, hunters, and outdoor enthusiasts.

TrailSeeker ED is packed with optical, mechanical, and ergonomic features that make it comparable to binoculars costing two to five times as much.


ED Objective Lenses

Extra-Low Dispersion (ED) glass virtually eliminates chromatic aberration, also known as color fringing, a visual defect common in binoculars. TrailSeeker ED delivers edge-to-edge sharpness with excellent color correction and razor-sharp images.

Not all ED glass is created equal. Celestron’s high quality ED glass delivers visibly brighter, sharper images compared to non-ED binoculars. The difference is especially apparent in low light conditions, such as at dawn or dusk.

Coatings and Prisms

TrailSeeker ED features fully multi-coated optics and phase- and dielectric-coated BaK-4 prisms. A binocular can be considered “fully multi-coated” when all air-to-glass surfaces are coated with multiple layers of anti-reflectivity coatings so that the maximum amount of light passes through the glass to the eye.

The prism inside TrailSeeker ED is made of high quality BaK-4 glass with both phase and dielectric coatings so that more light is reflected off the prism and diverted through the eye. Taken together, fully multi-coatings and BaK-4 prisms maximize light transmission for the brightest, most detailed images possible.

The Body

TrailSeeker ED is composed of lightweight and durable magnesium alloy. Its tough, rigid frame is coated with rubber to stand up to hard use in the field. What’s more, the binocular is fully waterproof and filled with dry nitrogen gas to prevent internal fogging of lenses. TrailSeeeker ED can stand up to even the toughest out-door conditions.

Viewing through TrailSeeker ED is comfortable for both eyeglass wearers and non-eyeglass wearers alike, thanks to the durable twist-up eyecups. Twist through multiple click stops to find the position that works best for you.

"I am very pleased with these binoculars, they are just right for bird watching from my conservatory and are not too heavy or bulky. They feel very well constructed and have a quality feel about them. The picture is sharp and detailed. Castle Cameras took my order and supplied the binoculars in a timely and professional manner. I am happy to recommend both the binocular and the supplier. Thank you."

"Coming from Bushnell Legend 10x42 binoculars, I'm happy with those Celestron Trailseeker 10x42 ED. Image is brighter with less chromatic aberrations. They are lighter as well (nice for hiking). Focus is a bit harder though (Bushnell were smoother to operate) and (consequently?) I have the the impression image is not quite as sharp as Bushnell's. But it is hard to tell. Thanks to Castle Cameras for their friendly support."
