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.

This is a really good mount and I’ve had good success with the XYZ alignment. There is a moderate amount of takeup in the adjustment pegs but it’s a good movement damped with grease probably.Problem is this the astronomical equivalent of buying a £200 white t shirt and it being identical to a £5 one. I’ve got a cheapo chinesium one for a spotting scope and it cost about £10. And honestly I think it performs equally.Sometimes quality in the brand is essential and my 8SE is a great example but accessories sometimes just have a badge on.

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.

Fits well and stays put. Holds the phone securely with minimum wobble. The XYZ adjustments are great and they don’t shift. Used this with a Celestron Nexstar 4 SE for showing the Moon to schoolchildren.However: The bottom of the holder obscures the headphone/charging port on an iPhone 8 and I would imagine other phones as well. This means you can’t use the remote shutter / charging facility on your phone whilst it is mounted.Also when holding a phone the platform ‘sags’ by a few degrees so that the phone is not perpendicular to the eyepiece. It’s not too noticeable but enough to throw any photo’s out of focus over the width of the image. In the photo the bottom is in focus whilst the top is slightly out of focus. You can alleviate it by raising the base of the phone but I would have expected something more robust from Celestron. There was some ‘give’ in the gears which could be cured by tightening a few screws but the plastic construction was the main source of the bending.

At first I thought this would be a good addition to my celestron telescope so I could use my p20 Pro. It’s fiddly to get to sit right in the first place as the bracket needs a substantial bit of lens to grip onto and even then isn’t particularly rigid. It has a lot of adjustment so has that in its favour but if you have the option of a t adaptor to a proper camera then go for that. I have since bought the t adaptor for my sony A6000 and had that up and running in minutes.I can’t comment if the cheaper phone brackets are any worse but this was very expensive for what it is and I will be looking to sell it on as I certainly won’t be using it again.
