The NexYZ Universal 3-Axis Smartphone Adapter for Digiscoping fits all eyepieces with a diameter of 35 mm to 60 mm without the need for an adapter. You can use it with telescopes featuring 1.25" and 2" eyepieces, as well as with spotting scopes, monoculars, and binoculars. With the two included adapter rings, you can also use NexYZ on slimmer (microscope) eyepieces down to 25 mm in diameter. A strong spring and a threaded locking mechanism ensure a secure grip on the eyepiece of the optical instrument, keeping the smartphone safe. The NexYZ is compatible with a wide range of smartphones up to 92 mm in width. It can be adjusted to fit any device, typically even when the smartphone is in a protective case. Even large "phablets" like the iPhone 8 Plus and the latest Samsung Galaxy devices work perfectly, with a distance from the camera to the bottom of the smartphone of up to 160 mm. The secure platform easily supports the weight of these heavy devices. If multiple people want to take photos through your optics, you can quickly swap one device for another thanks to the spring clamp. NexYZ is the ideal solution for star parties or group birdwatching, where everyone wants their own picture of the action.
