Celestron 81055 NexYZ 3-Axis Universal Smartphone Adapter, Patented Design - Works with Telescopes, Spotting Scopes, Binoculars, Monoculars and Microscopes, Black

This is a great device. Yes it is a bit tricky to set up, but one you have it on it does make it very easy to get better pictures than you would just hand holding. Biggest issue is as you move it about to line it up, the iPhone keeps switching lenses, but you can get there. Attached are a couple of pictures. On is lemon cells and the other is grains of salt. The attachment is flexible and fits ok on the Apex, although as a binocular microscope the second eyepiece does make it slightly snug. The plastic adaptor fits well and the phone felt secure. Alignment movement feels pretty good, although a bit rougher than I expected. Overall I think it is well made and good quality..

Great product. Holds phone in place and easy to adjust. Item is durable and well designed. Moderate weight so gotta be a bit careful on telescope not to tilt it once phone in place.

I bought the Celestron NeXYZ despite the mixed reviews, for my fieldscope rather than telescope. I have got the adaptor working well now after experimentation: 1. It is important to tighten all the screws, as well as the tensioning screws (but not too far as to inhibit smooth xyz movements). 2. My main issue was that the focal point of the phone camera lens was repeatedly off centre from the focal point of the eyepiece image requiring more digital zoom and a reduction in photo quality. I thought this was due to the use of multiple lenses on my phone. In fact, I noted that the phone was at a skewed angle to the eyepiece - this was because on the adaptor the eyepiece clamp and phone clamp did not align and was slightly off-level. There is no way to adjust this on the adaptor, which is a flaw the manufacturer has missed and would have been easy enough to incorporate. I managed to align the eyepiece and phone clamp by inserting a little piece of plastic as a 'spacer' in the rear screwed fixture. This sorted the issue nicely. 3. It is important to ensure the eyepiece clamp is correctly fitted so the phone is level to the eyepiece. This is is quite simple after a few go's. 4. This adaptor works much better on wider ocular eyepiece lenses, which is logical as there is a greater image diameter to align the phone lens to. 5. I found my stock camera app to be of little use, best to experiment with others which allow better manual control. Pro Camera X on Android works well. This adaptor is very useful in the way it allows xyz movements, allowing fairly swift alignment with the ocular image. However, the off-level alignment with the eyepiece and phone clamp on the adaptor is an issue and is probably as result of the polymer plastic construction. This is an easy fix, however, for a price tag of £50, I do feel that I shouldn't have to. I am happy with this adaptor now I have fixed the issues, although I do wonder whether cheaper models would do just as good of a job.

I’ve been looking for an adapter for my Bresser Messier AR 90s for some time and it wasn’t until I saw this on another site that I decided to go for it. It’s a little more expensive than other adapters but the quality is excellent and the numerous adjustment nobs make it very versatile. I wished I’d bought it sooner. It’s brilliant and works perfectly with my iPhone XR and my daughters iPhone 11 even with the cases on although they are thin cases so larger cases may need to be removed.

All the criticisms of previous viewers are correct. I'll add a few other observations. But first - it's not bad. In many ways it's a great idea and has great features. The x,y,z movements are solid; excellent rack and pinion. And it's nice to have the phone supported at the bottom as well as the sides - an uncommon feature and surely a necessity. But this is quite an expensive device, considering that simple mechanical equivalent attachments are £10-15, so I'd expect more, especially from Celestron. There are the following flaws: 1. The eyepiece grip has several flaws. It's designed for device eyepieces which are smooth or flat (cylindrical) in the axial direction. For eyepieces which may have a protruding step part-way along their axis, like my binoculars, this means that the clamp is not fully engaged along the full axial extent of its design contact. Combined with the foam material chosen for the clamp contact surface, this has lead to permanent indentation of the foam material, within a few hours of operation. This means that future use will simply require further pressure to maintain a good grip, leading to further compression of the foam .... Some form of adapter would be nice, especially for the price. The provided split corrugation wasn't a good enough design for my situation. 2. The marketing does not make it explicitly clear that the primary market is for phones with the camera lens in the corner of the smartphone body. This is an issue for e.g. Galaxy Note 9 etc with the phone in the mid-width position, since the z-axis adjustment and the design of the clamp axis can cause interference between the phone and the joint/bracket of the eye-piece mount. Not a major issue, but in conjunction with the axial dimension of the eyepiece grip, the axial dimension of the eyepiece grip joint, this can make getting the axial position of the camera a bit tricky, especially if it needs to be closer to the binocular eyepiece. 3. For binoculars it's very much a right-eyepiece device. If the eyepiece is a bit loose, then under certain orientations, the combined weight of the Nexyz and phone can twist the binocular eyepiece thus adjusting the focus. Bit of a nuisance. 4. The material of the rack and pinions was good enough and the assembly and operation of them were fine. Quite impressed. However, the rest of the structural material is a semi-hard plastic which is actually quite flexible. This means that the assembly is flexible under load (see point 5), and also that the manufactured assembly is not quite correct. It is quite clear from inspection that the component which holds the phone is misaligned with the plane of the eyepiece, and the axis of the rack-and-pinion to which it is attached, and is also slightly twisted across its width. For the price, and given the design effort, I expected the material choice and manufacturing / assembly execution to be better. 5. There is clearly quite a bit of flexibility in the structure. Several millimetres of clearance between the eyepiece and the camera support plate can be take up with the slightest of pressure, and this flexibility shows up when the camera is loaded, and the binoculars are tilted. The strength of the rack and pinion adjustment (in all three axis) combined with the weak grip of the eyepiece mean that in-situ adjustment can be fiddly. The structural strength of the combined assembly is inherently weak at the rack and pinions - don't know what they could do to design that out... 6. Protruding screws in several places. Will they fall out? For the price, you'd think they'd throw in a couple of cheap jeweller's screwdrivers and some instructions on how to fine tune and adjust the assembly. Would I buy it again? Probably not. Do I wish I'd read the other reviews before purchasing? Yip. Will I return it? No, it'll do. And I may even dismantle it, and modify it, to overcome some of the above defects. Maybe. Some rainy Sunday afternoon. Or maybe I'll stick to my Gosky mount. And by a telescope with a T-mount for my DSLR.

I have had several attempts at astrophotography using T adapters, DSLR, celestron neximage cameras, smartphones....they are all very very fiddly and difficult in the darkness. I have bought less expensive smart phone adapters but they just don't work. For me this is really good because it is so easy to use compared with other adapters for the phone. Firstly it can grip large lenses. Second the up-down, left right controls are on the same knob one above the other and are easy and to hand which gives instant and real solid control. Third and most important there is a different knob to move the lens of the smart phone (once aligned properly for the view through the lens) closer or further away from the lens of the telescope. The other cheaper adapters I have tried have no similar control and you have to loosen the adapter and prize the adapter up and down the lens in the dark to find the sweet for focus spot which is irritating and difficult. I don't have a mount that tracks the skies so the planets drift in and out of view and there are only so many things you can monitor at once. With this adapter once set up with the smart phone set with a 5 second delay to reduce vibrations all I have to do is keep the planets in the eyepiece. After only 5 mins I managed to get a picture of Jupiter's moons and Saturn. I hope to do a lot better when I work out what the iphone and all the Apps can do but I was surprised at the results for my first quick attempt. So this adapter is a little pricey but compared to a DSLR or Neximage it was so easy and it came up with a result and if you want to begin photographing planets there are so many Apps you can try to take and process your pictures, I used an iphone SE 2020 and Celestron 8SE telescope.

The packaging could not be better, no waste and totally safe,, plus for me this arrived on the Monday when I was expecting it to be on Wednesday in a couple of days time. The quality seems very good and I have just tried this with my A71 and Opticron scope taking a photo out of my bedroom window. It was very easy to set up, might take me a little while to get used to which knob does what but everything works really well, so well, I shall end up selling my Sigma 150-600mm f5-6.3 DG OS HSM Sport lens for my DSLR Camera :-) I will add a photo in the next few days after I have visited a local deer park, though the weather needs to get better first!

If I had bought an unbranded, cheap and nasty product of this type from eBay, and found it didn't work, I'd have been disappointed, but not surprised. After all, sticking your phone camera up to a telescope is hardly a natural thing to do, and I'd expect it to fail more often than it worked. But this is a branded product from a reputable manufacturer, and it's expensive. So I was bitterly and profoundly disappointed when I found it didn't work. Here are only some of the problems. - The clamp that holds the phone sort-of folds over the edges of the screen -- right where the camera controls are. It's difficult to set up the camera software when the phone is in the clamp. - The advertisement says that the device will work even with a phone in a case. That's clearly untrue if you have a case that folds open, because the clamp prevents it opening. - The device is in two parts, joined only by the rack-and-pinion mechanism that adjusts the distance between the phone and the eyepiece. This mechanism is not made to tight tolerances (that's putting it politely) and it wobbles. So when the phone is in the clamp, it moves with respect to the eyepiece at the slightest movement or vibration. This makes both alignment and focusing difficult. - It's very difficult to get the phone near enough to the eyepiece so that the image fills the screen. Or, frankly, is even visible. The minimum distance between the back of the phone and the nearest part of the eyepiece clamp is about a half-inch, and that's only if some part of the clamp does not foul the telescope body. - There are, as promised, three axes of adjustment. However, the control for one of these is hard to reach when the phone is mounted. I found that, with a lot of fiddling, I could sometimes get an image. But this required three hands to hold everything steady, and I didn't have a fourth hand to operate the camera controls on the phone. I tried with two different phones (Note 8 and S10e) and telescope, binoculars, and a rifle scope. No amount of fiddling gave me a picture that was in proper focus, and there was horribly chromatic fringing even on the best shots. I think the fringing is caused by the optical axes of the camera and the eyepiece can't be brought into proper alignment. I'm amazed that some people have been able to get decent pictures with this device. I can only imagine that they were lucky, or not very fussy. OK, so it's a phone camera, so I wasn't expecting miracles. But I didn't expect the device to be so impractical to use, nor the results so awful.

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 found the smartphone adaptor to be very sturdy and what I would expect from a company like Celestron. It attaches easily to my dobsonian and once I got the knack of adjusting it I found it very good for taking pictures with my cell phone. I bought it to look at the eclipse and tried it out on the sun with very good results (of course using a proper sun filter). I have not used it for looking at planets or the moon but from what I have experienced so far I know it will not disappoint.

Antes de comprar este adaptador, me costaba mucho trabajo y tiempo tomar buenas fotos con el celular a través del ocular del telescopio por el movimiento natural e involuntario de las manos, para tomar buenas fotos el teléfono debe estar totalmente estático y este adaptador es la solución. Se acopla muy bien a cualquier ocular ya que lo he probado con oculares pequeños e incluso grandes de 2". El tornillo que tiene de seguridad hace bien su función para apretar firmemente el adaptador al ocular. La capacidad de movimiento en 3 ejes que tiene (horizontal, vertical y profundidad) es perfecta para encontrar el punto exacto de enfoque de cualquier teléfono aún con cámara gran angular. Caben perfecto la mayoría de equipos, lo he probado con equipos grandes como el IPhone 13 Pro máx, Samsung S23 ultra, Honor magic pro y todo funciona bien, pero debes quitar las fundas para que entren sin problema o sin forzar el adaptador. Con el uso debo reconocer que se va aflojando poco a poco el mecanismo y a veces el peso de los equipos no se mantiene en el eje de profundidad, pero esto se resuelve apretando nuevamente los múltiples tornillos que refuerzan todo el mecanismo de desplazamiento de los 3 ejes (agrego foto), una vez hecho esto, como nuevo. Solo una advertencia, si tu celular tiene las cámaras en el lado derecho(la mayoría de equipos las tiene en el lado izquierdo o centro viéndolo desde la parte trasera), tendrás un problema ya que el eje de desplazamiento horizontal tiene un tope que impide que la cámara (si esta del lado derecho) llegue al centro de la mayoría de los oculares, lo cual limita su uso con este tipo de equipos, de lo demás va de maravilla. Para todas mis tomas y videos he utilizado solo celulares y he obtenido muy buenos resultados gracias a este soporte. Lo recomiendo.

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.
