2″ → 1.25″ RotoLock Visual Back Adapter

Description

A William Optics visual back adapter that converts a 2-inch connection to a 1.25-inch RotoLock eyepiece holder. The RotoLock mechanism securely clamps 1.25-inch eyepieces and accessories with a simple twist action, eliminating the need for thumbscrews and preventing accidental drops. This adapter is useful when you want to use 1.25-inch eyepieces in a 2-inch focuser with the added security of the RotoLock system.
