The 8x42 TrailSeeker ED binocular provides high-level outdoor
performance, making it a perfect choice for avid birders,
hikers, 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. Celestrons 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. Whats 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 outdoor 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.
Perfect for a Variety of Uses
TrailSeeker ED features a close focus of just 6.5 feet,
making it perfect for viewing birds, butterflies, plants, or
other nearby subjects. But this 8x42 binocular also offers
the magnification needed to get great views of distance
subjects, plus a wide field of view so you can easily follow
them as they move. No matter how you choose to observe, this
versatile binocular is an excellent all-around performer.
Ways to Observe
TrailSeeker ED includes both a neck strap and a carrying
harness so you can choose the option thats most comfortable
for you. Its also tripod adaptable, so you can mount it on
any standard photographic tripod for extended viewing or
digiscoping sessions. (Tripod adapter sold separately.) The

transport.
