This high-quality adapter is designed for the 3.5-inch focusers used on large FLT refractors from William Optics. It acts as a visual back and uses the "Twist-Lock" or "ClickLock" clamping method. By turning the locking ring, eyepieces and accessories are held securely and gently, preventing any tilting. The Rotolock is screwed directly onto the 3.5-inch extension tube of the FluoroStar refractor using a threaded connection. The eyepiece side provides a standard 2-inch opening.
