Product Description
Baader 2" ClickLock eyepiece holder for M56 thread of many Skywatcher and Celestron telescopes, precise locking onto the optical axis without force also avoiding locking screws marring barrels. Designed completely different to normal locking systems (screwing direct to the barrel), the ClickLock System presses multiple rollers radially to the inner part causing accurate centering precisely. Especially useful for photography, this is essential as the sensors need to be accurate to the optical axis.
Fits directly to M56 threads on focusers of many SkyWatcher & Celestron Telescopes
