The Explore Scientific BT-82 SF giant astronomy binoculars pair 82mm objective lenses with long eye relief for comfortable, wide-field stargazing. Large astronomy binoculars let you observe with both eyes for a natural, immersive, three-dimensional view of the night sky — and at 82mm they gather plenty of light for deep-sky scanning while staying more manageable than the largest giants.

Built for tripod use with interchangeable eyepieces, the BT-82 SF offers generous eye relief that's especially comfortable for eyeglass wearers during long observing sessions.

Who it's for

Great for deep-sky observers who want immersive wide-field binocular views with large aperture and comfortable, long eye relief. New to the hobby? See our guide on how to pick your first telescope.

Key features

  • 82mm objective lenses for strong light-gathering in each eye.
  • Long eye relief for comfortable viewing, including with eyeglasses.
  • Two-eyed observing for immersive, natural, wide-field views.
  • Interchangeable eyepieces for flexible magnification.
  • Tripod-ready design for stable, comfortable sessions.

What you'll see

The BT-82 SF frames large star clusters, bright nebulae, and Milky Way fields with a striking sense of depth. It shows the Andromeda Galaxy, the Pleiades, and big open clusters beautifully, resolves brighter globulars, and delivers detailed, comfortable views of the Moon — all using both eyes.
