50.8mm (2 ) Helical Focuser for visual and photographic use.

The product features a nose piece diameter of 50,8mm (2 ), when unscrewing the adapter it features a M48x0,75mm female thread.

On the opposite side there is a M48x0,75mm male thread on which it s possible to directly attach a reflex camera (with T2 wide) or CCD. It s also possible to attach a 2 eypiece or a reducer (from M48 to T2).
