Specification Brand : Astromania BulletPoint1 : Almost 3D observing possible: In addition to eliminating eye fatigue associated with viewing through one eye for a prolonged period of time, this bino viewer also provides a three dimensionaleffect while observing many celestial objects.Using both eyes means that an observer experiences a much heightened spatial feeling, as compared with observing through a telescope using only one eye. BulletPoint2 : With 1.85x and 3x specially-designed Barlow Lens: An excellent accessory which helps to reduce eyestrain. Eyepiece diopter scales for sharp focus. 1.85x and 3x specially-designed Barlow Lens is included which effectively doubles the magnification of eyepieces used. BulletPoint3 : Two 32mm Plossl Eyepicecs: With two 32mm Plossl Eyepicecs which give the widest viewing field along with extra sharpness and long eye relief. The unit has room for inserting two 1.25" eyepieces. The eyepieces are held in place by compression ring which keeps them securely in place without scratching them. BulletPoint4 : Multi-coated BAK-4 prisms: The Stereo Binocular Viewer will also improve contrast on deep sky objects as well as solar system objects. The Stereo Binocular Viewer is designed to work with Schmidt-Cassegrain telescopes (SCT) and many refracting telescopes. The Stereo Binocular Viewer requires you use two eyepieces of equal focal lengths and optical design. The BAK-4 prisms are multi-coated on their optical surfaces, reducing reflections to a minimum. BulletPoint5 : With their adapted 1.25" barrel, Astromania bino-viewers will fit into any standard telescope. The interpupillary distance is adjustable between 60mm and 77mm, so almost any young people or adults can use these bino-viewers.
