Description

The Explore Scientific BT 82mm ED Giant Binocular is a premium astronomical and terrestrial optics instrument built for serious observers who demand the best in clarity, brightness, and immersive viewing. Featuring large 82mm objective lenses paired with Extra-Low Dispersion (ED) glass, these giant binoculars gather exceptional amounts of light while minimizing chromatic aberration for razor-sharp, color-accurate views. Whether you're sweeping across the Milky Way, studying detailed lunar features, tracking planets, or scanning breathtaking daytime landscapes, the BT 82mm ED delivers a level of optical performance that standard binoculars simply cannot match.

Designed to be mounted rather than handheld, the BT 82mm ED is a true observatory-grade instrument that pairs perfectly with the Explore Scientific U-Mount and Tripod (sold separately) for a stable, fatigue-free viewing platform. Right out of the box, it comes ready to observe with a pair of included 62° 20mm Waterproof Eyepieces, offering a wide, immersive field of view from your very first session. For dedicated stargazers, nature enthusiasts, and astronomy clubs, this binocular represents an investment in optical excellence you will appreciate every time you look through it.


Key Features

  • Extra-Low Dispersion (ED) Glass: Dramatically reduces chromatic aberration and color fringing, delivering sharper detail, higher contrast, and more accurate color reproduction across all lighting conditions.
  • 82mm Objective Lenses: Large aperture gathers significantly more light than smaller binoculars, revealing brighter deep-sky objects, rich star fields, and vibrant daytime landscapes.
  • Premium Included Eyepieces: Comes with a pair of Explore Scientific 62° 20mm Waterproof Eyepieces for a wide apparent field of view and an immersive observing experience right out of the box.
  • Giant Binocular Design: Built for serious astronomical and terrestrial performance - ideal for sweeping the Milky Way, exploring lunar craters, observing planets, and scanning distant scenery.
  • Mount-Ready Construction: Designed for stable mounted use rather than handheld operation - compatible with the Explore Scientific U-Mount and Tripod for smooth tracking and full optical performance.
  • Reduced Chromatic Aberration: ED elements minimize unwanted color fringing around the Moon, bright stars, planets, and high-contrast terrestrial subjects for cleaner, crisper views.
  • Waterproof Eyepieces: Included 20mm eyepieces are waterproof-rated, making them reliable performers in varied outdoor conditions.
  • Wide 62° Apparent Field of View: The included eyepieces provide a spacious, panoramic viewing experience ideal for sweeping star fields and deep-sky exploration.

FAQ

Does the BT 82mm ED come with a tripod or mount?

No - the tripod and U-Mount shown in product images are not included with the BT 82mm ED Giant Binocular. Because of its size and weight, this binocular is designed to be used on a sturdy mount rather than handheld. Explore Scientific offers a compatible U-Mount and Tripod that pairs perfectly with this binocular and is available separately.

Can I use these binoculars handheld?

Due to their large 82mm aperture and overall size and weight, the BT 82mm ED Giant Binoculars are designed for mounted use rather than handheld operation. Attempting to use them handheld would result in image instability that significantly diminishes the observing experience. A compatible mount and tripod are highly recommended to get the full benefit of their exceptional optical performance.

What can I observe with the BT 82mm ED?

The BT 82mm ED excels at a wide range of both astronomical and terrestrial subjects. Astronomically, it delivers stunning views of the Moon, planets, star clusters, nebulae, galaxies, and rich Milky Way star fields. For daytime use, it provides sharp, color-accurate views of distant landscapes, wildlife, and scenic vistas. The ED glass ensures high contrast and minimal color fringing across all of these subjects.

Can I swap out the included eyepieces for different ones?

Yes - the BT 82mm ED is designed to accept interchangeable eyepieces, giving you the flexibility to experiment with different magnifications and fields of view. The binocular comes ready to use with the included pair of Explore Scientific 62° 20mm Waterproof Eyepieces, but upgrading or swapping eyepieces is a great way to customize your observing experience over time.

What is the warranty on the BT 82mm ED Giant Binocular?

The BT 82mm ED is backed by an Explore Scientific limited warranty. To activate your full warranty coverage, you must register your product within 60 days of purchase. Visit the Explore Scientific website for full warranty terms and conditions.
