Usage Tips:NexYZ fits any eyepiece from 35 mm to 60 mm in diameter including telescopes with 1.25inch and 2inch eyepieces, spotting scopes, monoculars,and binoculars. NexYZ will also attach to microscopes with the addition of the included adapter ring, which takes the usable diameter down to 25 mm, the size of a standard microscope eyepiece. A strong spring and a threaded twist lock provide a two-level strong and secure grip on the optical instrument's eyepiece so you can image with confidence. NexYZ also accommodates a huge range of smartphones. The phone platform is fully adjustable and can fit any device-usually with the case still on. Even larger "phablets" like the Plus and latest Galaxy devices work perfectly. The secure platform stands up to the weight of these heavier devices with ease. If multiple people want to capture a shot through your optic, NexYZ's simple spring-loaded clamps easy to remove one device and replace it with another in seconds. NexYZ is the perfect solution for star parties and group bird walks where everyone wants their own shot of the action.
