This adaptor holds an iPhone 12 mini with its cover on top of a telescope eyepiece with diameter 31mm. The wide camera (bottom camera) is centered on top of the eyepiece. Both phone and eyepiece have a tight fit so that nothing moves during use.
Tested on an iPhone 12 mini with the official leather case, on top of a National Geographic AZ 60/700 refractor telescope.
Zooming the camera to 2x allows the whole camera area to be filled with the eyepiece view. Adding a camera delay allows the telescope to stop shaking before the picture is taken.
P.S. Clouds are still a problem :)
