    Opticron USM-2 reviews

    USM-2 Universal Smartphone Mount for Digiscoping is rated 5.0 out of 5 by 1.
    Rated 5 out of 5 by from Great Design!! Quick and accurate mounting. Easy to align my iPhone 6 camera with the hole, and mounts securely with four curved supports. Camera also aligned with eyepiece without need for constant adjustments like other mounts I have used. You will need to focus scope before placing mount. Zooming in with iPhone camera fills the screen and picture quality is acceptable (see attached).
