the universal opitical smartphone adopter

[william martin]

Anyone here use a Carson universal opitical smart phone adopter with your telescopes???

 

If the adopter tends to slip off because of the foam rubber ends, try to remove the foam rubber tips off and use piece s of texture rubber tubing

 

You can make a cardboard tube to fit over the eye piece and cut to the right focus length  using the smart phone camera over tubing .

It works.
