Vixen Optics BT125-A overview

  • 1Description

The Vixen BT125-A astronomical observation binocular, with its interchangeable eyepieces and enormous light gathering power, is an undeniably great setup for high-powered observations both celestial and terrestrial.  Unlike its little brother the BT80M, this doesn't have shorter refractors with built-in barlow lenses-instead, the BT125-A has two true 760mm f/6.08 achromatic refractors (instead of 450mm + incorporated barlows), allowing it to have both wider fields of view with longer eyepieces and a higher maximum useful magnification thanks to its broad 125mm objective lenses.  And all the while you'll be astounded with the light gathering power that's more than 300x greater than human eyes.  Imagine the views of the Milky Way!

The BT125-A has permanently attached 45° prisms, to make for comfortable observing whether you're looking at stars or earthbound objects.  It accepts the entire lineup of Vixen Lanthanum & Lanthanum Wide 1.25" eyepieces.

For its remarkable depth perception and contrast, there is nothing that beats the ease and comfort of erect image binocular viewing.  Expect high quality observing of terrestrial vistas and celestial views alike, in a package which isn't difficult to transport to your favorite dark sky location out beyond.  Take a drive to nowhere on a clear, new moon night and be amazed!  You might even see a comet.

This is the version of the BT125-A that's just the binocular body-you must supply eyepieces and a mount.  Choose a beefy tripod preferably with either a robust geared head or a professional-quality fluid video head, such as those listed here as accessories.

Twin 760mm f/6.08 achromatic refractor telescopes with 45° incorporated erect image diagonals

Built-in handle and dovetail(for use with Vixen telescope mounts) with three 1/4"-20 threaded sockets
