SMARTOSCOPE UR-4 Adjustable Eyepiece Adapter

The SMARTOSCOPE UR-4 is a high quality, adjustable eyepiece adapter ring which securely attaches to the optics rail of SMARTOSCOPE VARIO-ADAPTER via a 30mm thread.

It is the gateway between the smartphone adapter and the eyepiece and allows connection to most spotting scope eyepieces from small to large.

Four adjustment screws engage the inner compression ring which is used to secure the adapter ring on to your eyepiece without damaging or marking the eyepiece cap.

The ring includes adjustment rubber strips to reduce the inner diameter of the adapter ring for extra versatility and compatibility to most eyepieces of any brand.
