• A complete digiscoping solution: NexGO connects your smartphone to your optic eyepiece
• NexGO’s design works with most optics including telescopes (with most 1.25” eyepieces), spotting scopes, binoculars, monoculars, and microscopes.
• Folds up for easy transport and storage.
• Charge your phone during use.
• Features two directional knobs (X-, and Y- axis) that perfectly align your phone’s camera with the eyepiece in seconds.
• Stands up to rigorous field use thanks to its robust, durable construction with a metal frame and polymer body.

The NexGO Universal Smartphone Adapter is a great first step into the world of astroimaging or digiscoping. The NexGO provides you everything you need to capture sharp, detailed images and video.

NexGO fits any eyepiece from 25.4mm (1.0”) to 44.45mm (1.75”) in diameter, including most telescopes with 1.25” eyepieces, spotting scopes, monoculars, binoculars, and microscopes.

NexGO accommodates a wide range of smartphones including the latest devices from Apple, Samsung, and Google. The phone platform is fully adjustable and can fit any device—usually with the case still on. For older phones that are 5” tall or less, the NexGO includes a booster to ensure the fit with the device.

Precise Alignment
The NexGO sports rack and pinion X- and Y- fine adjustment knobs for precise alignment and it folds up to a smaller size for easy transport.  Secure the NexGO smartphone adapter to your eyepiece by tightening the orange knob which will clamp the unit around the eyepiece.

Maximize your storage space when traveling or not in use, the NexGO smartphone adapter collapses to a compact configuration for easy transportation and storing.

NOTE: The X and Y adjustment racks come calibrated from the factory, but should you need to adjust them, go to the Support & Downloads tab and read our Tension Adjustment Guide for details.

Robust Construction
The secure platform stands up to rigorous field use thanks to its robust, durable construction with a metal frame and polymer body.  The NexGO will stand up to years of outdoor adventures.

Easy as Ever
Most adapters rely on you placing your phone perfectly on the platform and only offer limited adjustments. But NexGO gives you the power to place your phone on the platform, center it over the eyepiece with the X and Y adjustment knobs until you have the entire field of view in your shot. 

From start to finish, the process only takes about 30 seconds, including the time it takes to insert the phone into NexGO, attach NexGO to an eyepiece, start the camera app, and center the camera over the eyepiece using the knobs.

Switching phones, eyepieces, or optical instruments, requires only slight adjustments to re-center the camera over the new eyepiece. If multiple people want to capture a shot through your optic, NexGO’s simple spring-loaded clamps make it easy to remove one device and replace it with another in seconds. NexGO is the ideal solution for star parties and group bird walks where everyone wants their own shot of the action.

You can also switch your image from portrait to landscape simply by turning the padded eyepiece clamp and readjusting the X- and Y-axis to realign your phone with the eyepiece.

NOTE: NexGO is compatible with telescopes, spotting scopes, binoculars, monoculars, and microscopes. NexGO works with most phone cases, but if you have an especially large phone case with built-in batteries or a folio-style case, you may need to remove it.

NexGO Smartphone Adapter Instructions

1. Unfold your NexGO, and make sure the clamp is locked in with the main assembly.
2. Connect the NexGO to your eyepiece
   Position the clamp around the eyepiece and tighten the orange clamp knob until secure.
   This can be done with the eyepiece remove from the optical device, if you choose.
3. Attach your phone
   NexGO works with most regular phone cases, but you will need to remove “folio-style” cases. To insert your phone, pull the spring-loaded slider out. Place your phone on the platform, making sure the bottom is touching the rubber base. Then release the slider. Your phone should now be secure and ready for imaging. If it feels a bit loose, you may need to make tension adjustments to the rack and pinion system to keep the phone firmly in place. To do this, reference Tension Adjustment Guide under Support & Downloads.
4. Align and shoot
   Open your camera app. Center your phone camera over the eyepiece by adjusting the X- and Y-axis knobs. Finally, adjust the focus using the focuser on your optics and snap the image.
