The "HandyHaltDO" universal smartphone adapter features a durable metal clamping mechanism that secures the eyepiece from four sides, making it compatible with eyepieces with a diameter between 26–47 mm. Unlike conventional adapters that attach only to the outer edge of the eyepiece, this design allows mounting slightly further inward for a more stable and secure fit.
It also supports a wide range of smartphones with a width between 54–94 mm.
Suitable for use with astronomical telescopes, microscopes, and other optical devices with eyepieces.
