ZWO Helical T2 to 31.75 mm Crayford Focuser – Fine Focus Adapter
DESCRIPTION
The ZWO 31.75 mm helical Crayford focuser offers exceptionally fine focus adjustment, perfect for setups demanding precise focusing (from planetary imaging to wide-field astrophotography). It is mounted inline between an ASI camera and a T2-threaded filter wheel or accessory.
Its Crayford design ensures backlash-free operation under load, while the helical knob provides smooth incremental focus movement. Input is T2 male/female (M42×0.75) and it outputs 1.25" (31.75 mm), making it highly versatile. The anodized aluminum construction ensures rigidity and light weight. Ideally suited for long focal lengths and barlow configurations.
