- Revolutionary precision 3-axis design: The telescopic phone holder provides precise 3-way adjustment (up/down, left/right, forward/backward) to align your phone camera with the eyepieces. The Z-axis adjustment adds eye relief, helping you capture clear images and videos of celestial objects, wildlife, and distant subjects. - Full metal construction, no sagging: Built from a rigid aluminum alloy for strength and durability. It resists bending, tipping, or warping, keeping your phone perpendicular to the telescope eyepiece. Enhanced stability reduces wobble, and rubber pads on the eyepiece clip and phone clamp protect your devices. - Precision fine adjustment: Fine-tuning knobs allow meticulous, easy adjustments for razor-sharp alignment. The firm grip keeps your phone and eyepiece securely in place for reliable imaging. - One fits most: Compatible with nearly all Android smartphones (width 60–87.5 mm / 2.36–3.44 in). The adapter also fits most telescope, spotting scope, monocular, and microscope eyepieces (outer diameter 22–61 mm / 0.86–2.4 in). - Practical use scenarios: Capture starry skies and planetary images through a telescope; photograph distant wildlife with a spotting scope; document microscopic or classroom observations with a microscope adapter.
