CelestronSmartphone Adapter for Telescope, Binoculars & Spotting Scopes – Capture Images & Video Through Your Optics – Simple, Durable, Metal Body - Compact and Travel-Friendly

Doesn’t work with my scope

Excellent, design and so easy to use. Quality is good. This was a gift and my brother loves it.

High quality materials and stable when mounted. Wireless shutter release works, but it's not totally reliable. The phone mounting knob fell off, but that may have been my fault. It's held on by friction (screw threads would have been better), but I was able to press it back on well enough. Mounting is a bit tricky until you figure it out. You have to provide some eye relief (distance between the phone's lens and the telescope's eyepiece), much as you would when looking directly into the eyepiece. That means you have to clamp it high on the eyepiece, where the rubber of the eyecup meets the eyepiece. But once mounted, it's stable enough to focus easily and of course, to snap photos.

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.

Fits perfect

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.

Got this for my phone phone it works great really really good. Great value for the money good design fits great on his phone

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.
