Baader 31.75 mm to T-2 Adapter with Helical Focuser

Baader 31.75 mm to T-2 Adapter with Helical Focuser

DESCRIPTION

The Baader 31.75 mm to T-2 adapter features an integrated helical focuser offering 5 mm of smooth and precise optical travel. Designed for critical alignment of 31.75 mm accessories, it provides a secure and centered interface to T-2 threaded systems (M42 x 0.75). Its rotatable design allows precise distance adjustments without moving the optical setup.

Three M3 clamping screws ensure a tight and centered fit, while an additional M3 locking screw fixes the rotation at the desired position. This makes it especially useful for reticle eyepieces, autoguiders, or planetary cameras where fine focus or orientation adjustment is essential.

With a compact 47 mm diameter and weight of only 50 g, the adapter integrates seamlessly into all Baader and compatible T-2 systems. It’s the perfect solution when mechanical precision and optical consistency are required.
