ZWO Spiral Focuser 1.25\u2033<\/strong><\/p>\n\n\n\n

ZWO's Helical focuser is designed for extremely precise manual focus<\/strong> in compact setups. This model is particularly suitable for use with a off-axis guider (OAG)<\/strong> or small astro cameras where space is limited but precision is crucial.<\/p>\n\n\n\n

On the telescope side, the focuser has a female T2 thread (M42x0.75)<\/strong> and on the output side a 1.25-inch mount<\/strong> as well as a male T2 thread - offering versatile compatibility with eyepieces, planetary cameras and guiding solutions.<\/p>\n\n\n\n

Thanks to the spiral mechanism, the connected accessory rotates not along while focusing<\/strong>, preserving the orientation of sensors or prisms. The desired focus position can be secured with a clamping screw<\/strong> to prevent shifting.<\/p>\n\n\n\n

With a displacement of 6 mm and a fine adjustment of 0.1 mm, this focuser is well suited for applications where micron precision is desired, without motorization.<\/p>\n\n\n\n
