Does not fit
Standard spotting scope yet this will not fit over lens. Thrown in the rubbish bin. Do not buy this cheap tat.

Works like intended
I first struggled to align the camera with the eyepiece. Then, I found YouTube videos on how to do it. Search YouTube for "connect your phone to any telescope" or "telescope mobile holder."

Flimsy
Like to give things a chance but this is just cheap and plasticky tat. Not really fit for purpose. Christmas cracker springs to mind.

Good value phone mount
Seems reasonable quality for the money, can be a bit fiddly to set up properly but once set up it takes good photos .

I took this out and tried it today. Spent about 30 minutes trying to get it to work. I just could not get it to perform. It was just too busy for me trying to get it to focus in on the end of my spotting scope. I like the fact they do have a adapter built inside that will come out for bigger ends in your eyepiece. When I started using it, I didn't realize that came out and I was trying to get it over top and I was complaining the whole time. I finally figured it out that it was just an adapter for smaller ones. The one that came with my spotting scope work better than this one to get everything lined up. It is built very well and it may be exactly what you're looking for but for me it did not work very well.

This inexpensive little adapter did manage to hold my iPhone 8 Plus against the eyepiece of a monocular mounted on a tripod for a few birdwatching photos. It fit the monocular only once I removed one of the "V" braces. It's very finicky to set up, requiring fine adjustments to get to the exact center of the monocular's eyepiece, and the adapter has no provision for fine adjustment, just a wingnut to tighten onc everything's lined up. The location of the iPhone's camera lens also allowed some light to bleed through even once it was adjusted to best view. The spring-loaded clamp to hold the phone is very secure, very strong, but makes repositioning the phone in the clamp a two-handed job. Certainly a good value and an inexpensive accessory, but one that requires patience to set up and use. It did clamp to my tripod easily enough, and produced some reasonably good pictures.

It does not fit my phone well enough to see through my camera lens to take a picture.
