Designed to work with nearly any smartphone and a wide range of optical devices—telescopes, spotting scopes, binoculars, monoculars, and microscopes—this versatile adapter makes it easy to capture images and videos of the world around you. Secure the adapter to your eyepiece by tightening the eyepiece clamp, which locks the adapter firmly around eyepieces ranging from 29mm to 45mm in diameter, including most 1.25” telescope eyepieces. Place your smartphone in the adjustable phone clamp, which holds your device securely in place. Then use the alignment knob to position your phone’s camera precisely over the eyepiece for a clear, sharp image. You can also rotate your smartphone adapter 90* to switch between portrait and landscape orientation as needed. The Smartphone Adapter is a great choice for star parties and group bird walks where everyone wants their own shot of the action. Whether you’re observing the Moon through a telescope, photographing wildlife through binoculars, or exploring tiny details under a microscope, the Celestron Universal Smartphone Adapter makes it simple to capture and share your discoveries.

Title: Does what’s needed.
Review: Enough adjustability to align with my funky flip phone. Makes taking photos through the scope many times easier.As a nice little bonus, I found I was able to get everything lined up and then easily remove/replace the entire phone and apparatus to switch between using my eye and my camera.Didn’t notice any stability issues.

Title: Just a good product with a major flaw
Review: I like that metal part that attach to the eyepiece is metal and feels really sturdy, however the phone adapter is another story, specially the knob to tighten your smartphone. It just broke in less than a month, so disappointed right now because I love this brand.

Title: Trip to Alaska!
Review: This smartphone adapter for the celestron binoculars was difficult to get the hang of at first, but so worth it. We took it on our trip to Alaska and it allowed us to see so much wildlife we wouldn’t otherwise have been able to see. We were able to take pictures through it, but also zoom in with our phones to see more. It was well worth it even after getting the hang of it. Don’t get too frustrated, just keep messing with it until you can get it right. The only annoying part was trying to switch between phones because you had to readjust all settings because the camera locations are different on different phones.

Title: Nearly impossible to attach to binoculars by oneself
Review: I got this as part of a bundle with a pair of Celestron binoculars. Its nearly impossible to attach it correctly on your own, it really needs a third hand to attach (one to hold the binoculars, one to hold the phone in the exact right position, and a third to tighten the back screw). Some other negatives:- The space between the eyepiece holder and the phone mount point is to shallow. For the Celestron binoculars that it came with, attaching the eyepiece holder securely to the eyepiece, the eye cups stick out further than the phone mount bed, so the phone can’t be attached flat against the bed.- As mentioned above, it really takes 3 hands to correctly mount to binoculars. Might not be a problem with a telescope, but it was bundled with binoculars, so I expected it to work with them.- As you tighten the back screw to keep the phone in the right place, even if you’re careful tightening it causes it to tilt the phone slightly. This adjusts the phone’s view, making it not centered unless you take that into account with the phone’s position before tightening it.- The rubber mount points for both the eyepiece and phone are not soft enough. If you tighten it too much, you can break your binoculars or phone.The adapter would be 1000x better if the phone placement adjuster didn’t allow the phone to move freely, and instead worked similar to the phone bed screw, where tightening/loosening it would adjust its position.

Title: Sturdy Metal Construction & Easy To Adjust Precisely
Review: Ready to use out if the box. Well constructed. It’s easy to use and has a very precise mechanism which allows the user to align the camera to the eyepiece. Can be used with binoculars, telescopes and microscopes. It would be better if it were constructed from a lighter weight metal. Make sure that the 1.77 in capacity for the diameter of your eyepiece is enough. My binoculars had a 1.5 inch eyepiece, however the rubber eyecups brought the diameter to just over the maximum capacity of the unit. If your eye pieces are 1.5 in and have rubber cups, then I recommend that you purchase the Celestron – NexYZ DX Kit – 3-Axis Universal Smartphone Adapter. I am awaiting delivery of one of these models today which allows for up to 2 inch eyepieces. I will continue to use my present unit for my microscope and my telescope.

Title: Está bien, hace el trabajo.
Review: Leí muchas reseñas, de todas las calificaciones, hoy recibí el adaptador y puedo afirmar:- Funciona para la mayoría de móviles, sin importar si la cámara está a la izquierda, al centro o a la derecha. Muchas opiniones decían que para cámaras ubicadas al centro no funcionaba, falso, si funciona.- No es difícil de configurar, con anterioridad vi un video de un compatriota colombiano que me dio las pautas principales a tener en cuenta. 1. Verificar cual es la cámara principal del móvil, 2. de día enfocar con el telescopio un punto medianamente lejano, 3- quitar el ocular e instalarlo en el adaptador, 4- poner el móvil en el adaptador y asegurarlo sin afectar botones del móvil. 5- Luego encender la cámara y mover el brazo del adaptador con el móvil instalado hasta cuando en la pantalla del móvil aparezca un circulo perfecto y blanco, en ese punto asegurar el brazo del adaptador con el perno correspondiente. 6- Colocar el conjunto, adaptador y móvil, en el telescopio. Funciona. Mi primera foto, faltó foco, otra recomendación del video es hacer esto de día, lo hice de noche.- Muchas reseñas negativas hablaban del problema del perno que asegura el móvil al adaptador, se rompía a la primera, yo estaba prevenido y lo aseguré con cuidado, no se rompió y estaré pendiente a ver como se desempeña en el futuro.En resumen me parece un buen producto, no es perfecto, las soluciones más profesionales son considerablemente más costosas y es adecuado como un primer paso hacia la astrofotografía.Desde el hermoso Caribe colombiano feliz noche.
