SVBONY Universal Cell Phone Adapter Mount Telescope Phone Mount for Binocular Monocular Spotting Scope Telescope Support Eyepiece Diameter 25 to 48mm

This device actually works very well. I’m very pleased.

Me parece bueno, útil y con cuerpo de metal, ideal para las observaciones, lo malo que en mi caso al momento de apretar el celular comprime las teclas de audio, pero por el resto perfecto

This one, the older model, works much better than the one supplied with their spotting scope, though it is bigger and bulkier than their newer one. I can get it to lay flat on the eye piece where as the newer one supply just wouldn't go there. The only advantage the newer model had over this one is it had a spring attachment for the phone, where as this one uses screw pressure. But all in all this one is definitely better...IMHO.

I purchased this adapter for my 100mm telescope and planned to use it with my iPhone 16. Unfortunately the build quality is lacking and although it will physically accommodate a larger phone, it seemed unstable to me. Also, the 2 Axis mount lacks precision adjustments so while the mount is attached to the telescope, there is potential for the phone to slip out of the slot and fall while trying to line up the lens and tighten the thumb screw. For these reasons I returned the adaptor and purchased a more expensive product. I gave this adapter 3 stars because it will work, it just lacks the quality that I prefer and would function better with smaller phones.

1. While setting it up on a carpeted floor, I left my iPhone XR in the adapter that was on the right eyepiece of a binocular set up on a camera tripod for all of 2 minutes. The phone crashed to the floor. Also came down with it the rubber grip that is supposed to clamp on the phone from both sides. Why is the rubber grip not glued onto the frame? Luckily, since I was not working on a hard surface, the phone survived.2. Design flaw - the phone holder part of this contraption should be up and away from the surface by a good 0.5 - 0.75 inch to allow for the phone camera to rest on the eye relief that most binoculars and eyepieces have. It is not - and a struggle ensues.3. Hard to position the lens to align with the eyepiece - forget about an easy clamp you might have been thinking of when buying it.On the positive side, it is cheap. Not much else to add to it - oh, and the construction seems OK as well. Barring the shortcomings above, which are enough to shake your confidence in trying to use it in a dark place, and the potential of a costly repair on your phone screen, plus the struggle that you may undergo to use it, it is alright. I am constantly in need of small objects that I can use to hone my aiming skills in my basement, and this looks like a very good candidate. I wonder if a .177 pellet at 1300 fps from a distance of 40 feet would have a lasting impact on it or not.

Por lo que se paga me parece correcto. El producto me llego en buen estado. Cumple fielmente con el propósito con que fue diseñado.

This worked great with my iPhone 7, but it is just barely big enough for the iPhone 10 in a case. You need to make sure that your phone is perpendicular to your lens or the image will not be complete and will be distorted. I find it easier to take the lens out of my telescope and put the camera and lens together in my car where I can use a flashlight to help me line everything up. The moon also works. I have also used it with my monocular to take pictures of the moon. Again, it is easier to line it up using a flashlight or streetlight than while everything is on the tripod. I included a shot of the moon. Anyway, this is cheap and works well. I may order another so that I can use this with students for stargazing and have one to set up while the other is in use.

Takes practice, and this is not a great picture but it is an OK shot. For my casual use this is a great value.Excellent affordable option to expand your older telescope without a built in imaging sensor.
