The Artesky 1.25" precision helical focuser (SKU: HELIX-31) enables precise focusing for eyepieces and cameras with a 1.25" barrel or T2 (M42 × 0.75) thread. The focusing mechanism, based on a precision worm screw, ensures smooth and stable movement without rotating the eyepiece barrel, which distinguishes it from simpler helical models. Its compact design and low weight make it ideal for mobile and autoguiding setups.
