Celestron Basic Smartphone Adapter (#81035) Simple, sturdy, and ready to shoot.The Celestron Basic Smartphone Adapter lets you turn just about any optical instrument into a digital imaging platform—whether you’re photographing lunar landscapes, tracking birds through binoculars, or capturing tiny details through a microscope. This no-frills adapter is a lightweight, field-ready solution for turning your smartphone into a capable eyepiece camera in seconds. A Universal Fit for Most Optics This smartphone adapter is compatible with virtually any eyepiece that measures between 29mm and 45mm in outer diameter, including the vast majority of 1.25" telescope eyepieces. Whether you're using a spotting scope, binocular, monocular, or microscope, the adapter securely fastens to your eyepiece and centers your phone’s camera over the exit pupil. It’s a perfect fit for most smartphones—from iPhones to Androids—and usually works with your phone case still on. (Oversized cases like battery packs or folio styles may need to be removed.) Fast Setup, Steady Results No apps. No wires. No learning curve. Just place your phone in the adapter, line up the camera lens with your eyepiece, and gently tighten the locking knobs until everything is snug and secure. The metal frame provides excellent rigidity, reducing the chance of movement during exposure. It’s a reliable, repeatable setup whether you're shooting stills or recording video. Once attached, you can capture high-resolution images, share them live, or text your results straight from the eyepiece. The adapter is especially handy for outreach events, science classes, or documenting observations in the field. Rugged by Design Constructed from durable cast metal, the Basic Smartphone Adapter is built to withstand regular use, changing weather, and the occasional bump in the gear bag. Whether you’re observing from a mountaintop or a backyard patio, this adapter won’t let you down.
