The flagship of Explore Scientific's giant binocular line. The BT-150 ED pairs two 152mm objectives with extra-low dispersion (ED) glass for bright, color-pure views that a single telescope simply cannot match — using both eyes delivers a dramatic sense of depth and detail on star clusters, the Moon, comets, and rich Milky Way fields.

  • Twin 152mm (6-inch) objectives with ED glass to minimize chromatic aberration
  • Comfortable 45-degree angled viewing position
  • Accepts standard 1.25" astronomy eyepieces, so you can change magnification like a telescope
  • Individual helical focusers for precise dioptric adjustment
  • Adjustable interpupillary distance

An instrument of this size requires a heavy-duty support: pair it with the matching Explore Scientific U-Mount and tripod for the BT-150 (sold separately). Free US shipping and 30-day returns.
