LAKWAR Telescope Phone Adapter, Unviersal Cell phone Mount Compatible Binoculars, Monocular, Microsope, Spotting Scope, Telescope, Smartphone Holder Clip Bracket fits almost of Mobile phones

Haven't really used it much but seems to do the job.

very cheap made broken after little use cant hold the phone close enough would not recomend to buy .

Fits my binoculars without the inner rings and with some tightening of the knob on the side. Takes some getting used to when holding the binoculars with the phone, but in all it does the job perfectly. Will likely work on other sizes too. Happy to have bought!

I brought this due to good reviews. This does not attach to telescope once phone is attached, and falls off. Very tight fit round phone causing scratches as you try to insert and remove phone.

I've tried a few mobile phone attachment gadgets to use with my telescope/digiscope . The adjustable alignment type can be fiddly and time consuming to fit and when you do get to snap a pic your subject has flown or the gadgets moved out of alignment!! This design definitely fits on the scope eyepiece easily with the chosen supplied collar and stays in place .. however I found this one left a small gap between the eyepiece and the lens of the phone camera which permits light to detract from the shot .. maybe it was my scope or my phone design but I will continue to search for a similar interface that has an adjustment to mate the eyepiece and phone lens together with no gap ...

Tried several variations but found this one's mechanism to be the most straightforward to set up without having to make countless adjustments to line everything up

Does the job,just a very small gap between holder and telescope lens

Works fine with my scope
