- 3-axis precise alignment (patent pending): Up/down, left/right, and forward/backward adjustments align your phone camera with the eyepiece. The Z axis provides eye relief for clear images and videos of celestial objects, wildlife, and distant subjects. - All-metal construction, no sagging: Made from rigid aluminum alloy for stability and durability. Securely holds the phone perpendicular to the eyepiece, reducing shake. Rubber pads on the eyepiece clip and phone clamp protect devices from scratches. - Universal compatibility: Fits most Android smartphones (width 2.36-3.44 in / 60-87 mm) regardless of camera design. Adapts to eyepieces with outer diameter 0.86-2.40 in (22-61 mm) on most telescopes, spotting scopes, monoculars, and microscopes. - Precision fine adjustment: Designed for razor-sharp alignment with easy-to-reach fine tuning knobs and firm grips to keep the phone and eyepiece securely in place during use. - Practical use scenarios: Digiscoping for distant wildlife and birds, astrophotography or videography of planets and stars, and field observations through scopes or microscopes. This adapter improves stability, accuracy, and image quality across setups.
