Almost 3D Observing Possible: A binocular viewer turns your telescope into binoculars; unlike the common and rather un-natural one-eye observing way; you can observe in a fully relaxed manner without squinting and experience a stronger sense of space
Equipped with Two Additional Eyepieces: Two 1.25-inch 34mm Plossl eyepieces are firmly secured in place with compression rings without scratching them; a stereoscopic binocular viewer requires two eyepieces with the same focal length and optical design
