Celestron Stereo Binocular Viewer

Celestron Stereo Binocular Viewer

A binoviewer uses two matching eyepieces to allow you to get the most out of your observations. Your eyes will relax, and you’ll find that you can observe for longer periods of time without suffering from eye fatigue.

The Celestron Binocular Viewer is well-made, with a rubberized coating to make it easy to grip, even with gloves on. The 22 mm BaK-4 fully multi-coated prisms provide increased light transmission with no vignetting or light cut-off. Each eyepiece holder can be individually focused, and diopter adjustment readings are well marked. The 1.25” insert barrel is threaded for filters, allowing you to use one filter instead of threading them on each individual eyepiece.

The Celestron Binocular Viewer weighs about 18 oz and uses approximately 3.5" of back focus. This is sufficient for most catadioptric telescopes (Schmidt-Cassegrain, Maksutov-Cassegrain, etc.) as well as a good number of refractor-style telescopes. 

Not intended for use with newtonians, however with the correct adapters, this is still possible.
