This adapter fits on the eyepiece well, and secures easily enough. Be careful not to tighten it too much, as it could deform or scratch the eyepiece, but reasonable caution eliminates issues.The reason for the 3 stars, however, is the strength of the spring in the clip - I'm afraid to put my phone in it for fear it'll crack the screen or camera housing.

It barely holds my phone in a vice like death grip, and then makes it hard to adjust the view to see the eyepiece. Be aware that a lot of telescopes will not work for this style of photography. This product was received via Amazon Vine.

This does work, but I'm not going to use it in the long-term because I'm worried about it squeezing my phone too hard. I get that it has to squeeze hard to hold a phone in place when you put it on a telescope and let go, but it has a really tight spring grip and I would never naturally squeeze my phone that hard for fear of crushing it. Maybe phones are tougher than I expect, but I'm not risking a few hundred dollars to find out.That said, the product does work if you have a spare old phone you're willing to risk, or if you're just a risky person. It's adjustable so while at first I thought it wouldn't fit my S10+, I realized that I could extend the center of this out a bit so that it would fit afterall. Note that this requires the camera portion of your phone to be flat - any protruding portion of the camera and this might not fit flat against it. It has plastic clamps to hold the 1.25" eyepiece so no worry about damage their, it does hold everything in place and aligned so you don't get that weird glare or halo effect for shots that aren't aligned properly.

I had some concerns about this product because it grips the phone screen tightly, making me worried that it might cause damage. I managed to make it work with some tweaks, but I don't plan on using it again to avoid any potential harm to my phone.

I am an experienced amatuer astronomer and have wondered about just how well these kinds of cell phone mounts worked, and I have to admit I was pleasantly surprised. To start with, you have to make an adjustment to the mount so the opening in the mount is centered on the camera lens on your phone. Just set up your telescope on your target with the 1.25" eyepiece you want to use and get it focused. Position your phone and secure it in the mount, then place the mount over the barrel of the eyepiece and secure it with 6 plastic screws that keep the mount centered on the eyepiece. This is much like mounting a finder/guidescope in a ring mount. At this point, your phone camera should show the view through the eyepiece where you can make finer focus adjustments and zoom in as you wish on the image, and start shooting. I captured the two images of the Sun using a Pixel 7a phone and a Meade ETX90 EC telescope with a solar filter.There are two reasons I gave it a 3 star rating for stablility, both related to the clamp that attaches the mount to your phone. It works great if the back of your phone is perfectly flat. However, my phone has a raised bar across the back of the camera that sticks out maybe 1/16". This is enough that the mount wouldn't properly stay in place. The first picture above shows the same problem on an old phone that I no longer use. To get around this, I place two spacers on each side of that bar and then it worked fine. I couldn't get a clear pic of this, but just imagine two rubber spacers that sit on each side of the raised camera lens, so the clamp is pressed against the spacers and not just on the raised camera lens. The other concern I have is that the clamp has a screw that you can turn to increase the pressure the clamp exerts to secure your phone in place. The problem is, one side of the clamp is pressing against the back of your phone, the other is pressing against the screen. How much pressure do you want to put on your screen? I don't like that idea either, but while using it I found that the clamp strong enough that very little, if any additional pressure was needed to completely secure the phone. That said, it makes me a little nervous using it.Bottom line is that this mount works pretty well if you can get past the clamp pressing against your screen and work out how to deal with a raised area around your camera lens if your phone has that design.

It works as intended and provides a really nice attachment point for your camera.

I find it difficult to mount and get the camera lens to line up. Great idea but is difficult to implement.

My basic smartphone doesn't take night time pictures anyway, so I knew this wouldn't help, but there are cool birds nests I want to see better and take pictures of without using the camera zoom (which just makes them blurry), and I want to monitor and document some browntail moth activity that I'm a bit concerned about. Well, this phone/telescope adapter came in a little box with no instructions whatsoever. I did the best I could but I could not adjust the clip clamp in such a way that the lenses of the phone would stay lined up with the eyepiece. I just could not get a tight fit no matter what I tried.

As an amateur astronomer, I so wanted the Starboosa Smartphone Telescope Adapter to work, give me good results and to enable me to share some of the views that I get through my telescope. Unfortunately I got very disappointing results. I was using a 127mm Maksutov-Cassegrain telescope with a 25mm eyepiece giving me 60x magnification (the lowest I have), I tried with two different models of Samsung phones. Conditions were very good and I was viewing a half moon. Through the eyepiece I could clearly see craters on the moon in excellent detail. Once I attached the Starboosa Smartphone Telescope Adapter and tried to take photos, the results were poor (see photo). Maybe one could get better results with a different type of telescope and/or phone ? I do not know. A pity because the adapter design looks good.
