Celestron – NexYZ – Universal Smartphone Adapter for Telescope, Binoculars & ...

Works great with my Pixel 2xl! I tried another mount first (one of the cheaper ones that basically just screws clamps down on the phone and eyepiece) and they were extremely difficult to line up as any looseness necessary to adjust would allow the phone to move way more than was possible to control, and locking it down again would throw off adjustment again, plus the mount pressed down on the buttons on the phone, preventing proper use while in the mount. This mount is spring loaded for the phone holder, so placing the phone in is quick, easy and secure, plus it doesn't push down on the phone's buttons. There are adjustments for the X, Y and Z plane, so once the phone is in place, all it takes is adjustments of three knobs to line the phone up. I was unable to line up the other mount in any sort of reasonable amount of time or effort. This mount was lined up in about a minute. The clamp spring that holds the eyepiece is not strong enough to hold the phone level, but that's not an issue as there's a 'safety lock', which when screwed tight, keeps the clamp from opening, and securely holding the holder to the eyepiece. The X/Y/Z motion might be too loose when you get the mount to hold the phone steady in certain orientations, however there are small screws on the mount which control the force necessary to move those knobs, which can be adjusted from very loose to unmoveable. The manual does not cover this at all, which might explain some of the bad reviews, but once you know about them and adjust them as needed, you won't have any issues. The only 'issue' I've had is that the phone's camera is wide enough of an angle that there is vignetting on the corners of the image. This isn't an issue with the mount, but more of an issue with the focal length of the phone's camera, and the FOV of the eyepiece itself. If your phone has a 'zoom' lens or portrait mode, or perhaps if you have much more expensive eyepieces than I have with wider FOVs, then this might not be an issue. The image can also be zoomed in, digitally, or the final image cropped. Something to keep in mind. Great mount. Highly recommended.

Ok, so some people have noted the mount can be loose and the phone will not stay in position. This is a case where RTFM (Read The Fine Manual) would have saved the day. Each axis has two adjustment screws that tune the tension of the linear rails increasing the stability of the mount. Look up "NexYZ tension adjustment" on Google for the manual and watch my review video. Overall this mount exceeds my expectations. It is far sturdier than I expected, but not as sturdy as it could have been but enough to easily trust my note 20 ultra to it. Is it worth the money? Absolutely. Does it work as well as I would have liked? Not as well as I would have liked. However, this is the best mobile device digiscopeing mount I've found. It has metal rack and pinion gearing and well thought out adjustment mechanisms. It has generous fitment; a Note 20 Ultra fits with room to spare. The Eyepiece arm has excellent fitment and a very good tension adjustment mechanism. It works well on my large 2" Mead QX eyepiece. My real issue with it is the need to be able to move the phone out of the way to position, and reposition. The phone back over the eyepiece for long exposure. Secondly, you WILL need counterbalance weight if you are using a GOTO telescope. Please please please for the sake of your poor telescope's gears, do not use this without balancing your scope with your eyepiece, mount, and phone. Those are minor gripes and definitely not a deal breaker. There is no way you could get me to send it back. By far the best mount.

Before you read this; I am very new to this hobby, I’ve only had my telescope for just over 2 months. I bought this because I wanted to share the views I was getting with friends and family via social networks. That being said... The NeXYZ performs fairly well. The only reason I didn’t give it 5 stars is through no fault of its own. There is a lot of vibrations when attached to focuser (I figure because of its total weight with the phone in it) so I’d suggest using a timer. I also suggest getting an app that allows for exposure and ISO settings (look for DSLR Camera in the App Store). The phone I’m using is an iPhone 8 with an otter box case. The phone fits well and I’m comfortable with how much grip the device has to hold it securely. I’m using this on a Celestron 130 SLT with a 5.5mm Meade 5000 series EP and a 10mm Celestron Luminos EP. The NeXYZ is large enough to handle the large Eye Pieces but on the Luminos you need to set it so it doesn’t unscrew the eye relief piece (I found that hanging it at an angle of 4 o’clock works fine). The wonderful thing about the NeXYZ is the ability to move on all 3 axis’s. I have read just about every review for this on Amazon and yes, there is some fine tuning that is needed when trying to align the phone with the eye piece. I feel the device is well built and should hold me over until I can afford to do astrophotography with a real camera. In all, I would recommend this product. I have combed all of the internet and for my money this was the best option and well worth it. (Pictures: Orion Nebula, Moon, the $.99 app that I’m using)

I could secure my phone over the eyepiece of my telescope without breaking any sweat.

Utilisé sur Jumelle astro (sur trépieds) et télescope (sur des oculaires 1,25" via l'un des deux adaptateurs complémentaires inclus) avec un iPhone 13 Pro, je dois reconnaître que si cela demande plus de manipulations qu'avec un adaptateur T2 pour appareil photo (qu'il suffit de visser), cela n'en demeure pas moins génial. Les optiques sur smartphones sont de petit diamètre, et selon le modèle, elles ne sont pas placées au même endroit, et pire maintenant, les smartphones en ont plusieurs. Cela a pour conséquence de demander un peu de réglage préalable: - Choisir l'objectif du smartphone à aligner avec l'oculaire (quand il y en a plusieurs) - Trouver le réglage du logiciel de photo du smartphone permettant d'utiliser l'objectif en question - Aligner précisément (dans les 3 directions) l'objectif et l'oculaire Cela implique de passer un peu de temps la première fois en pointant sur un objet fixe et suffisamment lumineux (pour ne pas en plus galérer avec la mise au point logicielle du smartphone). Ensuite, il devient possible de faire de très belles photos souvenirs. Je n'ai pas encore regardé s'il est possible de procéder comme avec une caméra astro pour faire de l'empilement, mais déjà, pour quelques euros, on est en capacité de faire facilement des photos lunaires, planétaires, d'observation en journée, etc. Je n'ai pas encore eu de ciel suffisamment clair pour essayer sur des amas stellaires. Je pense que pour une utilisation avec un smartphone (solution "cheap" donc), c'est déjà très très bien ! J'ai apprécié la qualité générale de l'objet (pas de jeux sur les éléments mobiles, facilité et précision des réglages, possibilité de ne pas dérégler entre 2 utilisations. Franchement, c'est top !

I have used this to take some great photos. It holds firmly without any wobble and is super adjustable. Attached are a couple of images I took with my phone thanks to this adapter keeping it in the sweet spot over my telescope's eyepiece. Highly recommended.

A sturdy and well-engineered piece of kit. I used a week or so ago to get some shots of the moon from my backyard in the city. I was happy with the results using my iPhone X on both the wide and zoom lenses..
