Takahashi Eyepiece Adapter (31.7mm)

This beloved compression-ring adapter transforms any 2″ focuser or visual back with an M36.4 external thread into a ready mount for 1.25″ eyepieces, diagonals, or accessories. Built from machined aluminum with a satin-black knurled sleeve and a contrasting silver compression ring, the TKP00101 offers a smooth, secure grip that locks your eyepiece barrel firmly—no set screws, no scratches, just precision control.

With a 29 mm metal back-length, it maintains parfocality across your accessory load, and its robust construction survives repeated use under the night sky. It’s the essential bridge for anyone who appreciates both Takahashi quality and the convenience of 1.25″ setups.

Cloudy Nights Community Insight:
Observers routinely praise how this adapter “gives a rock-solid grip on eyepieces and prism diagonals” and talk about its smooth feel during cold-night handling.

Observing Tip:
Thread it directly into your Takahashi 2″ diagonal, extender, or barrel—its compression design means you can swap eyepieces in seconds, comfortably handling accessories that weigh far more than the adapter itself.
