Telescope Phone Adapter, Plastic Scope Phone Mount for Microscope, Monocular, Binocular, for iPhone, Samsung, LG and More Smartphone

It works pretty alright
This mount is better than holding your phone up to the eyepiece and trying to get the angle and distance just right.I would recommend setting it up during daylight hours, so you can be sure that you know what you are doing and that you can get everything set up correctly. I used a Moto G Play (without the phone case) and was able to get these pictures of Jupiter and the Galilean moons, something I could not really do without the mount.Please note, getting the exposure correct is difficult; Jupiter is not exploding in that picture, it is just over-exposed.As far as usability goes, the mount is ok. The phone holder arms are on a spring, so you have to pull them apart and then hold them apart while you insert your phone. When you release the arms, they close automatically.The screw on the back of the phone holder likes to stick – when you first unscrew it, the phone won’t start sliding up and down freely until you give it a little nudge. After the nudge, the phone slides freely until you tighten it.The eyepiece holder works well. It fits my standard eyepieces (I don’t have any special eyepieces, just the ones that came with the telescope – and the telescope isn’t anything fancy either).

Happy with purchase.
Originally I got the cheapest model offered. It was very easy to use and get on my phone, an S21 Ultra. The problem was that it holds the phone with a spring and was real tight. Since I just got my phone I didn’t want to risk the spring snapping back and causing a scratch. The seller was awesome and let me get the next model up with the screws to adjust tension. Much much better. Both of these not only attached to my telescope just fine but they also have a side mounting hole for a tripod. So this is like 2 mounts in one.Now the other issue as many have indicated is that it is a pain to get a camera phone lined up on a telescope hole. My S21 ultra has like 5 camera that the software seems to pick which is in use depending on zoom settings. So lining up the right camera hole is hard. What I did was put my telescope in my kitchen so I had a lot of light coming into the lens. Then I put the phone on there and adjusted the zoom settings to how I’d use them outside. Finally I adjusted the mount so I could see through my camera into the lens. I tightened everything and carried it outside and was able to see Jupiter as I intended.

A must have for space enthusiasts
My son got a telescope for Christmas and a friend of his recommended we buy this for him also. Don’t bother spending more on other adapters, this one is very well constructed with precise controls for the phone grip and lens grip. Both are padded and hold securely without jiggling around while you are moving the telescope. It is very easy to align the phone camera and there is enough room to move the bracket up or down the lens about a quarter inch if needed for picture width. The frame is well made and sturdy, so there is no worry of it flexing or breaking. Very sturdy and quality feel. Hard to believe it is so much cheaper than the other options of which many seem less elegant of a solution.

Meh
Did not fit my athlon spotting scope or my Steiner binoculars. I removed the insert and then clearanced the mainframe with a Dremel tool and now it barely slides over. Very cheap. The stretch portion of it that the phone fits in is only spring loaded. Stretch to maximum with my Galaxy s22 with an OtterBox case barely fits. Anything wider than that will not fit.
