BT 150mm ED Giant Binocular
Description
The Explore Scientific BT 150mm ED Giant Binocular represents the absolute pinnacle of binocular astronomy, pairing two massive 150mm optical systems - one for each eye - to deliver an observing experience that no conventional binocular or single telescope can match. Premium Extra-Low Dispersion (ED) glass dramatically reduces chromatic aberration and false color, producing cleaner edges, truer color reproduction, and stunning sharpness across every target from the Moon and planets to distant nebulae and galaxies. The sheer light-gathering power of dual 150mm objectives reveals dense star fields, rich open clusters, expansive nebulae, and brighter galaxies with a level of brightness, contrast, and detail that will leave even experienced astronomers breathless.
Binocular observing is a fundamentally more natural and immersive way to explore the night sky - using both eyes reduces fatigue and creates a sense of depth that mono-eyepiece viewing simply cannot replicate. The BT 150mm ED ships ready for its first night out with a pair of Explore Scientific 62° 20mm Waterproof Eyepieces, and its standard 1.25-inch interchangeable eyepiece design lets you dial in any magnification or field of view your targets demand. Designed exclusively for mounted use, this instrument pairs perfectly with the Explore Scientific U-Mount and Tripod for the rock-solid stability these optics deserve.
Key Features
- Dual 150mm ED Objectives: Two premium 150mm Extra-Low Dispersion glass objectives - one per eye - gather extraordinary amounts of light for bright, sharp, immersive views of deep-sky objects and more.
- Extra-Low Dispersion (ED) Glass: Significantly reduces chromatic aberration and false color around bright, high-contrast objects, delivering cleaner edges, improved contrast, and accurate color reproduction.
- True Binocular Deep-Sky Performance: Reveals faint stars, expansive nebulae, rich open clusters, the Milky Way, and brighter galaxies with detail and brightness impossible to achieve with smaller binoculars.
- Includes Explore Scientific 62° 20mm Waterproof Eyepieces: Comes with a matched pair of wide-field 62° waterproof eyepieces so you can start observing immediately right out of the box.
- 1.25-Inch Interchangeable Eyepiece Design: Accepts any standard 1.25-inch eyepieces, giving you full flexibility to customize magnification and field of view for any observing target or session.
- Designed for Mounted Use: Built exclusively for use on a stable mount - pairs with the Explore Scientific U-Mount and Tripod (sold separately) for smooth, comfortable sky navigation.
- Reduced Eye Fatigue: Two-eyed observing creates a more natural, comfortable experience during long sessions, delivering greater perceived depth compared to single-eyepiece telescopes.
- Terrestrial & Astronomical Versatility: Sharp, color-corrected optics perform beautifully on the Moon, planets, bright stars, open clusters, nebulae, galaxies, and terrestrial subjects alike.
- Limited Warranty: Backed by the Explore Scientific warranty - register your product within 60 days to activate full coverage.

FAQ
Is the tripod and U-Mount included with the BT 150mm ED?
No - the Explore Scientific U-Mount and Tripod shown in product images are sold separately. The BT 150mm ED is designed exclusively for mounted use, so pairing it with a compatible mount is essential for a stable and enjoyable observing experience.
Can I use my own eyepieces with this binocular?
Yes. The BT 150mm ED features a standard 1.25-inch interchangeable eyepiece design, meaning you can use any compatible 1.25-inch eyepieces you already own to adjust magnification and field of view. It also ships with a pair of Explore Scientific 62° 20mm Waterproof Eyepieces so you can start observing right away.
What can I observe with the BT 150mm ED?
The BT 150mm ED excels at a wide range of targets. Its massive 150mm objectives gather enormous amounts of light, making it superb for sweeping the Milky Way, resolving rich open clusters, viewing expansive nebulae, exploring bright galaxies, and studying intricate lunar detail. The ED glass also ensures excellent sharpness on planets and bright stars, and it performs well for terrestrial viewing as well.
Why is binocular astronomy better than using a single telescope?
Observing with both eyes is more natural, more comfortable, and more immersive than using a single eyepiece. Binocular vision creates a perceived sense of depth in the night sky, reduces eye fatigue during long sessions, and allows your brain to process more visual information simultaneously - resulting in a richer, more enjoyable observing experience overall.
What does ED glass do, and why does it matter?
Extra-Low Dispersion (ED) glass is a premium optical material that reduces chromatic aberration - the unwanted color fringing or false color that can appear around bright, high-contrast objects like the Moon, bright stars, or planet limbs. With ED glass, you get cleaner, sharper edges, more accurate color reproduction, and higher contrast, which is especially noticeable in a large-aperture instrument like the BT 150mm ED.
Does the BT 150mm ED come with a warranty?
Yes, the BT 150mm ED is backed by the Explore Scientific limited warranty. To activate full coverage, you should register your product within 60 days of purchase. Contact our customer support team for assistance with warranty service or product support.
