About this product

Model:  cel_nexyz_adptr
Part Number:  81055-CGL

NexYZ connects your smartphone to your telescope, spotting scope, binocular, monocular, and microscope so you can capture images and video through the eyepiece

“US and International Patents Pending”

NexYZ fits any eyepiece from 30 mm to 60 mm in diameter including telescopes with 1.25” and 2” eyepieces, spotting scopes, monoculars, and binoculars. NexYZ will also attach to microscopes with the addition of the included microscope 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 iPhone 8 Plus and latest Samsung 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 make it easy to remove one device and replace it with another in seconds. NexYZ is the ideal solution for star parties and group bird walks where everyone wants their own shot of the action.

Easy as X-Y-Z

What makes NexYZ different from other smartphone adapters? The three-axis adjustment. Most adapters rely on you placing your phone perfectly on the platform and only offer limited adjustment in two axes. But NexYZ gives you the power to place your phone on the platform, center it over the eyepiece with the X and Y knobs, and then move up or down over the eyepiece until you have the entire field of view in your shot.

And even though this adjustment is ultra-precise, it’s still quicker and easier than with other adapters. From start to finish, the process only takes about 30 seconds, including the time it takes to insert the phone into NexYZ, attach NexYZ to an eyepiece, start the camera app, and center the camera over the eyepiece using the knobs. If you switch phones, eyepieces, or optical instruments, you will need only slight adjustments to re-center the camera over the new eyepiece.

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

NOTE: NexYZ fits telescopes, spotting scopes, binoculars, monoculars, and microscopes. It will not fit riflescopes. NexYZ will work with most phone cases, but if you have an especially large phone case with built-in batteries or a folio style case, Celestron recommends removing it for optimal use.


  • NexYZ connects your smartphone to your telescope, spotting scope, binocular, monocular, and microscope so you can capture images and video through the eyepiece
  • Works with a wide range of mobile phone models, including all the latest devices from Samsung, Google, and Apple
  • Unlike other adapters, NexYZ features three directional knobs (X, Y, and Z axis) that perfectly align your phone’s camera with the eyepiece in seconds so you are ready to snap the perfect image
  • NexYZ stands up to rigorous field use thanks to its robust, durable construction with a metal frame and polymer body

Smartphone Adapter Instructions

  1. Connect The Adapter
    • For Telescopes, Binoculars, and Spotting Scopes

      Squeeze the lever to open the clamp. Position the clamp around the eyepiece and release. Tighten the safety lock.

    • For Microscopes

      Choose one of the two provided adapter rings that best fits your microscope’s eyepiece and secure it in place. (You may need to remove the eyepiece from the microscope to install the ring.) Then, follow the instructions above.

  2. Attach Your Phone
    • NeXYZ works with regular phone cases, but you will need to remove “folio-style” cases. Extend the slider. Place your phone on the platform, making sure the bottom is touching the rubber base. Release the slider. Your phone is now secure and ready for imaging.
  3. Align and Shoot
    • Open your camera app. Position your phone over the eyepiece using the X and Y axis knobs. Then, use the Z axis knob to move closer or further away from the eyepiece until you have achieved your desired framing. Finally, adjust the focus using the focuser on your optics and snap the image.

Excellent adjustability but not perfect
Monday, 22 February 2021  | 

Arrived in good time and well packaged, thank you. I have only tried this attached to my binoculars so far and I have found the range of adjustments very good and easy to use with my small iPhone SE attached. I have found that it is quite easy to inadvertently drive the X-Y axis into the Z plane such that the bracket bends, but that is something that I just need to keep an eye on. Once adjusted it should be avoidable. I have found the eyepiece grip wanting, the unit is heavy even without the phone, but the combined weight of my small iPhone SE and the holder means that it droops meaning that the phone is not perpendicular to the axis of view. The phone holder is also not completely square with the axis of view either which exacerbates the droop issue mentioned above.

On the face of it the Celestron NexYZ-Axis is a nice idea and is reasonably solid feeling for a plastic item, it is difficult for me to compare others of this type as I have not tried any other phone holder, and keeping things in perspective it is just for taking fun pictures with your phone, but it just doesn't feel 5 stars.

Good phone holder
Monday, 11 January 2021  | 

At first sight this seems like it might be an overly complicated piece of kit. There are so many adjustments! But once mastered, it provided a solid mount for my phone that was easy to remove and replace on my astronomical binoculars.

Game Changer
Wednesday, 30 December 2020  | 

What can I say, this is a game changer for taking images through your telescope. Nice and sturdy and lots of adjustment. If you have a bulky phone case then you might want to consider a more slimline case, as it can be difficult to get the camera lens close to the eyepiece if using say a 7.5mm. Apart from that its great. As I'm finding out, in the astronomy game you get what you pay for! Highly recommended for me, great holder! FLO are fantastic to deal with 🙂

First impressions

Speedy delivery from First Light at a good price!
Works well but only tested in daylight do far.
Noticed you cannot connect earphones to iphone to use as shutter release, since cable is obstructed by cradle.

Nice piece of kit but has issues
Monday, 11 March 2019  | 

Bought this to be able to share some of my observations with the rest of the family.
First this is a very nice and sturdy made piece of kit, aligning is easy and takes about half a minute to get it set just right. Plossls that are either fitted into 1.25" holder or are long enough for the adapters grip to secure over the eyepiece work well.
However the biggest issue I have with this, if the eyepiece is small and not set into a 1.25" holder then the adapter simply wont be able to open its grip wide enough to secure on the holder and would be too big to secure on the eyepiece itself.
If you have heftier eyepieces e.g. Celestron Luminos again the grip does not open wide enough to fit over the eyepiece.
