New from William Optics - 3.5" to 2" RotoLock Visual Back Adapter for FLT Series Refractors
Replace the standard 2" compression band eyepiece holder on your FLT series telescope with William Optics' new RotoLock Visual Back. Just rotate the adapter ring clockwise to lock any inserted accessory, or counter-clockwise to release the accessory. Innovative design ensures that you get a very solid hold and the accessory is perfectly centered every time. No thumbscrews to worry about! The internal ball bearings and detents make this adapter a joy to use.
Meant only for use on William Optics FLT telescopes with a 3.5" focuser. The original eyepiece holder can simply be unscrewed, and this new adapter can be screwed in its place. 1.25" eyepiece holder not included.
