360° Rotating Telescope Phone Adapter — Smartphone Mount for Telescopes

360° swivel and improved imaging: The adapter uses an upgraded swivel bearing to rotate the phone easily between horizontal and vertical framing while attached to eyepieces. The design moves the exit pupil about 10 mm closer to the phone lens, cutting down on the dark ring around the image and giving a broader usable field for stars, planets, birds and distant subjects.

Fast, four-step mounting: A one-piece slide rail and stretch clip streamline attachment. The installation is broken into four straightforward steps that eliminate fiddly threaded adjustments. The mechanism is intended to let you move from unpacking to shooting quickly so you spend more time capturing images and less time aligning optics.

Solid build and accurate alignment: The body combines a metal frame with polymer components for a balance of toughness and light weight. Reinforced screws reduce chances of optical misalignment, and the eyepiece clamp is treated with a non-slip surface. A strong spring (rated at about 6.6 lb force) keeps the phone held firmly to prevent unwanted shifts during use.

Compact for field use: This smartphone scope mount avoids heavy, complex threaded fittings. Its footprint is approximately 4.8 × 3.1 × 1.8 inches and it weighs roughly 0.22 pounds, so it fits easily into a jacket pocket or daypack. The small size makes it a practical companion for outdoor photography, astronomy sessions, and travel.

Broad compatibility: The adapter accommodates phones with widths between 2.6" and 3.7" (66–95 mm), including common models from popular manufacturers. It accepts eyepieces with outer diameters from about 0.79" to 2" (20–50 mm), so it will clamp to telescopes, binoculars, monoculars, microscopes, night-vision optics and spotting scopes. That range covers most consumer optics and smartphones on the market.
