10 Best Orion Astronomy Binoculars 2025 in the United States

The Celestron SkyMaster 15-35x70 binoculars are designed for astronomy and long-distance outdoor viewing, offering a strong zoom range from 15x to 35x magnification. Their large 70mm objective lenses gather a lot of light, which is great for seeing faint objects in low-light conditions like dawn, dusk, or night sky viewing. The BaK-4 prisms help provide bright and clear images, which is important when stargazing.

These binoculars are quite heavy at around 3.3 pounds and large, so they are best used with a tripod to keep your view steady, especially at higher magnifications. The built-in tripod adapter makes this easy to set up but keep in mind a tripod is not included. Coatings on the lenses and the water-resistant rubber armor improve durability and grip, making them suitable for outdoor use even in less-than-ideal weather. While the zoom feature adds flexibility, very high magnifications like 35x can make it harder to hold the image steady without a tripod.

Due to their size and weight, these binoculars might not be the best choice if you want something very portable or for quick handheld use. However, for those seeking powerful, clear views of the night sky or distant landscapes and who don’t mind using a tripod, these binoculars present a solid option backed by a lifetime warranty and good customer support from a trusted brand.

The Orion GiantView BT-70 binocular telescope is designed for intermediate astronomy enthusiasts who want immersive and bright views of the night sky as well as daytime scenes. With its large 70mm objective lenses, it captures plenty of light, making stars and details easier to see. The included 18mm eyepieces provide 22x magnification right out of the box, and you can swap eyepieces for different zoom levels, which adds versatility.

Its 45-degree angled eyepieces and individual focus adjustments make viewing comfortable over long periods. The binoculars are waterproof and nitrogen-purged, protecting them from moisture and fogging, which is helpful for outdoor use.

Weighing about 13.7 pounds and measuring 24 x 15.75 x 9.5 inches, it is fairly bulky and less convenient to carry compared to smaller models. If you prioritize image brightness and flexibility over lightweight portability, this model suits you well. Those looking for a more compact, lightweight option might find it a bit heavy to handle for extended stargazing sessions.

The Celestron SkyMaster 25x100 binoculars are designed for serious astronomy enthusiasts and long-distance viewing. With a powerful 25x magnification and massive 100mm objective lenses, these binoculars are perfect for stargazing and observing distant terrestrial objects. The large aperture allows for excellent light gathering, making them suitable for low-light conditions like early morning or nighttime viewing. The BaK-4 prisms ensure bright and sharp images, enhancing the viewing experience significantly.

Due to their size and weight, these binoculars must be mounted on a tripod (not included), and they are not practical for handheld use. The built-in tripod adapter makes it easy to attach to any standard photographic tripod. The rubber-armored housing provides durability and a secure grip, while the water-resistant feature offers protection against unexpected weather conditions. Celestron also offers a limited lifetime warranty and US-based tech support, adding to the product's reliability.

The need for a tripod and the XXL size might make these binoculars less convenient for casual users or those looking for portability. These binoculars are best suited for dedicated hobbyists and serious astronomers who require powerful optics and are willing to invest in a tripod setup.
