Product Description

Orion GiantView BT-70 45° Binocular Telescope

With 70mm objective lenses, the Orion GiantView BT-70 Binocular Telescope delivers an immersive experience while being very compact and portable.

  • 70mm objective lenses provide bright and immersive views of both starry skies and daytime terrestrial scenes
  • Accepts interchangeable 1.25" eyepiece pairs for a variety of magnification options (additional eyepieces sold separately)
  • Included pair of 18mm, 65 eyepieces provide 22x views out of the box
  • Waterproof and nitrogen purged, featuring comfortable 45 eyepiece orientation and individual eyepiece focusers
  • Weighs 6.6 pounds

Stargazing with two eyes provides an amazing amount of depth while also making observations more relaxing and comfortable. Views of everything from lunar craters to brighter nebulae will take on an almost 3D feel in the GiantView BT-70. These lenses gather 96% more light than 50mm binoculars, so you'll be able to see more objects in the sky with greater clarity. But the fun doesn't stop there! This binocular telescope becomes a fantastic "spotting scope" for terrestrial exploration during the day. The 45° eyepiece angle makes both daytime and nighttime observations comfortable.

The BT-70 includes a pair of 18mm 65° 1.25" eyepieces which provide 22x magnification and a 2.9° field. The included eyepieces are threaded for 1.25" filters which can be used to enhance the view. Individual eyepiece focus provides precise focus control, while compression rings hold eyepieces securely in place.

Our favorite feature of the BT-70 is its ability to accept pairs of 1.25" eyepieces so you can control power depending on your observing goals. For example, a pair of 10mm eyepieces will deliver a 40x view through the 400mm focal length BT-70. For the best results, we recommend using 8mm or longer focal length 1.25" eyepieces with the BT-70.

Since the GiantView BT-70 accepts eyepieces, you can also use pairs of 1.25" light pollution filters to improve contrast while observing brighter deep sky objects. With light pollution filters installed, the GiantView BT-70 provides incredible views of many star clusters and nebulae.

Thanks to its sealed and nitrogen purged body, the rugged BT-70 is waterproof for use in damp conditions, but it's not designed for permanent outdoor installation. The GiantView BT-70 weighs in at 6.6 lbs. and works on most sturdy photo tripods. A built-in threaded 1/4"-20 socket allows secure tripod attachment.
