This is a universal telescope imaging adapter for smartphone. It's the most convenient and light weight to carry around, to couple on binocular, spotting scope or any type of telescope.
The adapter fits eyepiece 1.25" and 2" barrel at any angles. As long as the smartphone is not wider than 10 cm, it's highly compatible.
Use it to snap a picture of Moon's crater or day time distant view at anytime without additional tools.
