The Optic Universal Adapter was created to make using the Phone Skope even more simple! The features of the universal include a ratchet-like, spring loaded, detent (catch/locking) mechanism that uses small plastic “fingers” that twist in and twist out creating a solid mount to most optics. The connector is available in 2 sizes.

Small U1 - fits eyepieces ranging from 1.20 - 1.90'' in diameter.

Large U2 - fits eyepieces ranging from 1.7 - 2.34'' in diameter

To complete your Phone Skope purchase, be sure to purchase a phone adapter also.  You will need both an optic adapter and a phone adapter to begin Phone Skoping!
