The wide taper design prevents accidental dislodgment, ensuring your observations remain uninterrupted. Moreover, eyepieces are firmly held in place with a compression ring lock, available for both two-inch and optional 1.25-inch holders (1.25-inch holder sold separately), safeguarding your investment from wear and ensuring a perfect fit every time.
