2" helical focuser for visual and photographic use; the connection is 50.8mm, unscrewing the fitting you have a female M48x0.75mm thread. On the opposite side we have a male M48x0.75mm thread on which it is possible to directly connect a reflex (with T2 wide) or a ccd or apply a 2" eyepiece holder or a M48 to T2 reducer.
The focusing movement is smooth and precise and unlike cheap helical focusers when you rotate the focus ring the end part moves forward or backward without rotating. On the focus ring there is also a millimetric graduated scale and two locking knobs. Length fully closed: 92mm (without 2" nose 57mm) Length fully extracted: 132.5mm (without 2" nose 97.6mm)
