Product Details

Add the Celestron Stereo Binocular Viewer to your repertoire and enjoy celestial views with more contrast and improved detail!

Our eyes work as a team, and our brains are wired to work with images that both eyes produce together. When we use just one eye to do observations through an optical device, the results are lacking somewhat in detail and contrast. 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 22mm 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 ounces and uses approximately 3.5 inches 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. Newtonians (including Dobsonians) and some spotting scopes have the least amount of back focus. Using a binoviewer on these designs will result in the inability to focus to infinity with most, if not all, eyepieces and hence we do not recommend these for reflectors and spotting scopes.

Remember, binocular viewers require the use of two matched 1.25" eyepieces, which are not included.
