Celestron 1.25" Smartphone Adapter DX Kit Bluetooth Remote

Smartphone adapter for 1.25" eyepieces

This kit attaches a smartphone to telescopes, binoculars, spotting scopes, monoculars and microscopes using a 1.25" clamp range. It fits eyepiece diameters from 29mm to 45mm with a thumb-screw hex clamp for a secure hold. The adjustable phone platform accommodates most devices even with a case fitted. A Bluetooth shutter remote is included for vibration-free capture.

Cast-metal construction for stable imaging

The adapter body is crafted from cast metal to provide a rigid platform that resists flex during long exposures or video recording. Threaded knobs lock both the eyepiece clamp and phone holder firmly in place, keeping alignment steady under the weight of larger handsets. This mechanical stability helps maintain sharp focus across extended astrophotography or digiscoping sessions.

Upgrades from basic universal holders

The DX Kit replaces simple friction-fit or plastic adapters that slip on heavy phones or lack fine adjustment. The precision thumb-screw phone clamp and metal eyepiece collar eliminate the trial-and-error alignment common with entry-level mounts. The jump is worth it when you need repeatable camera-to-eyepiece centring for planetary, lunar or microscopic work.
