Universal Smartphone Adapter for Optics

The Celestron NEXYZ 81055 connects almost any smartphone to telescopes, spotting scopes, binoculars, monoculars and microscopes. Its adjustable platform grips devices of various sizes, including larger phablets, while a supplied adapter ring fits standard 25 mm microscope eyepieces. A spring mechanism and threaded twist lock provide a secure two-level hold on the eyepiece.

Replaces Cumbersome Single-Purpose Mounts

This single adapter replaces separate holders for astronomy, birding and microscopy by covering eyepiece diameters from 30 mm to 60 mm. It handles 1.25" and 2" telescope eyepieces without additional parts. The jump is worth it when you image through multiple optical instruments and want one reliable mount that adjusts quickly between sessions.

Capacity and Headroom

The platform accommodates a wide range of current smartphones, securing even large models for extended imaging. It runs out when a phone exceeds the platform's maximum width or when an eyepiece falls outside the 30 mm to 60 mm range, such as certain specialty microscope or telescope eyepieces not covered by the 25 mm adapter ring.

Questions about this item

Will the adapter fit my telescope eyepiece if it measures 30 mm to 60 mm in diameter?

Yes, the NEXYZ 81055 clamps directly onto eyepieces from 30 mm to 60 mm, covering 1.25" and 2" telescope eyepieces as well as spotting scopes, monoculars and binoculars.

How do I attach the adapter to a standard 25 mm microscope eyepiece?

Use the supplied adapter ring; it slides over the 25 mm eyepiece and then the main unit locks onto the ring with its spring-loaded twist lock.

When should I replace the spring mechanism or twist-lock threads?

Replace them if the spring no longer holds the eyepiece firmly or if the twist lock slips during use; both parts are mechanical wear items that degrade with repeated clamping cycles.
