The Explore Scientific BT-150 ED is a giant astronomy binocular — a large-aperture binocular telescope that lets you observe the night sky with both eyes for a natural, three-dimensional, deeply immersive view. Each side carries a 150mm objective with extra-low-dispersion (ED) glass, so you get serious light-gathering power and sharp, colour-true images that far exceed ordinary handheld binoculars.

Two-eyed (binocular) viewing is famously comfortable and revealing: star fields look richer, and many observers pick out detail more easily than through a single eyepiece. Angled eyepieces make it comfortable to look up toward the sky, and interchangeable eyepieces let you change magnification to suit the target.

Who it's for: Serious observers who want immersive, wide-field two-eyed views of star fields, clusters, comets and the Milky Way. Curious how binoculars compare to a telescope? Read our guide to astronomy binoculars vs telescope.

  • 150mm ED objectives: large-aperture, extra-low-dispersion optics for bright, colour-true views.
  • Two-eyed viewing: comfortable, immersive, natural-feeling observation with both eyes.
  • Angled eyepieces: comfortable viewing toward the zenith without neck strain.
  • Interchangeable eyepieces: swap eyepieces to change magnification for different targets.
  • Built for astronomy: a giant binocular telescope for deep, wide-field sky views.

What you'll see: Two-eyed viewing through 150mm optics delivers stunning wide-field vistas — the Milky Way's star clouds, large open clusters like the Pleiades and Double Cluster, brighter nebulae and galaxies, comets, and beautifully detailed lunar views. The immersive binocular perspective makes sweeping the sky genuinely addictive.

Why observe with a giant binocular?
Using both eyes is comfortable and immersive, and 150mm apertures gather enough light to show clusters, nebulae and rich star fields with a natural, three-dimensional feel.

Do I need a mount for it?
Yes — a large binocular this size needs a sturdy mount and tripod for steady, comfortable viewing (available separately).

Can I change magnification?
Yes — it accepts interchangeable eyepieces, so you can adjust the power to suit wide-field sweeping or higher-power targets.

Is it better than a telescope?
It's different — binoculars excel at immersive, wide-field, two-eyed views, while a telescope reaches higher magnification on small targets. Many enthusiasts enjoy owning both.
