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.
- Binoviewers improve views dramatically, producing a three dimensional effect that you’ll love!
- Using two eyes for observing instead of one lets you see more detail, reduces eye fatigue, and increases contrast.
- For use with catadioptric telescopes and other telescopes with sufficient back focus.
- Includes an aluminum carry case with foam-lined interior.
- Requires a matching pair of 1.25” eyepieces, sold separately.
