Celestron Basic Smartphone Adapter DX with Bluetooth (#81037)
Snap the sky. Share the view.
The Celestron Basic Smartphone Adapter DX with Bluetooth is your all-in-one gateway to digiscoping and astroimaging. Whether you’re capturing lunar craters, distant birds, or microscopic details, this rugged, easy-to-use adapter holds your smartphone steady over a wide range of eyepieces—while the included Bluetooth remote helps eliminate camera shake for sharper shots.
If you’ve ever tried to hold your phone up to an eyepiece by hand, you already know how frustrating that can be. This adapter solves the problem—and makes imaging through your telescope, spotting scope, binoculars, or microscope a snap.
Designed for Everyday Observers
This adapter works with nearly any eyepiece in the 29mm to 45mm outer diameter range, including most 1.25" telescope eyepieces. It’s also a great fit for spotting scopes, binoculars, monoculars, and microscopes. (Just don’t try it with a riflescope—this model isn’t designed for that.)
The spring-loaded phone holder accommodates a wide range of smartphone sizes—from 56mm to 97mm wide (2.20" to 3.81")—and usually fits with the case still on. If you have a large folio-style or battery case, you may need to remove it for a secure fit.
Easy Setup, Steady Shots
Using the adapter couldn’t be simpler:
-
Slide your phone into the holder and tighten the adjustment knob.
-
Center your camera over the eyepiece using manual adjustments.
-
Tighten the eyepiece clamp to lock the adapter in place.
That’s it. Your phone is now ready to record the view. No slow-motion knobs or alignment guides needed—just quick, intuitive setup that gets you imaging fast.
The included Bluetooth shutter release remote makes it easy to snap photos or start/stop video recording without touching your phone—helping you avoid motion blur and keep your subject perfectly centered. It pairs with virtually any iOS or Android smartphone and includes a CR-2032 battery.
Built for the Field
The Basic Smartphone Adapter DX is housed in a tough cast metal frame that stands up to frequent use, travel, and varying weather conditions. It’s compact enough to stash in your backpack or accessory case, and tough enough to survive years of observing sessions.
