Don't let memorable moments slip away without capturing them with your smartphone. Use the FoneMate Universal Digiscoping Adapter from Tele Vue to connect your smartphone to a spotting scope or a telescope to use it as a powerful telephoto lens. The adapter is compatible with Dioptrx Eyepieces and will accept smartphones with minimum dimensions of 2.4 x 4.7" and maximum dimensions of 4.7 x 8.3". It is easy to mount and use and leaves most of the front and the sides of your smartphone exposed to allow easy access to its buttons, controls, and functions.
