Starboosa Universal Smartphone Telescope Adapter Mount - Work with Telescope Spotting Scope Microscope Monocular Binocular - Fits Eyepiece Diameter 25 to 48mm (0.98"～1.88")

I got this to use with my Google Pixel 7 on a small microscope. The clamp didn't screw all the way down to hold it tight against the eyepiece. I ended up taking one of the rubber edge protectors off the phone part and bent it to form an arch and electrical taped it in place. That helped. Because of where the camera is located on the phone, it's kinda hard to line it up straight up and down. I had to angle it in order for it to line up with the eyepiece. And the phone part of the bracket lined up exactly over the volume control on my phone, so if I tightened it, the music blared! I finally had to turn off the music and work with the sound of roosters crowing and baby goats hollering. Once I got the gizmo figured out, it works pretty good for the money.

Won’t fit on a Vortex spotting scope. Dimensions given show it will but not even close

Little bit hard to set it but it’s ok for money.

This mount is built well, but it will only work if the minimum focal distance of the camera matches the eye relief of the scope / binoculars etc. I would not bother with this type of clamp again unless I see some sort of adjust ability foe that.

Love it! Very beautiful. Just the right size. Not big and faulty like others I saw. Very pleased with it. Been wearing it since it arrived which was very quick by the way.
