So we already had a Phone Mount for our Microscope and wanted one for our Telescope as well. As they are quite expensive I thought I would design a very easy to print / use adapter sleeve to make the phone holder/mount interchangeable. I took a quick look but didn't find any pre made as these two devices usually don't require any interchangeability.
This adapts sizes from 23.2mm (common microscope diameter) to 1.25" (this is the most common/standard telescope eyepiece size.
I have attached pictures showing the same phone mount attached to both the microscope and telescope for reference.
We have a OMAX Trinocular microscope, and a Orion SkyQuest 8" dobsonian telescope however this should work for a ton of different brand applications.
We purchased the phone mount from Amazon for $45 CDN. It fits small phones all the way up to plus size phones with cases. It fits my Samsung S20 Ultra with a case on it no problem.
