New from William Optics - 2" RotoLock Eyepiece Adapter / Visual Back with 2" SCT Female Thread # D-ROTO-A2-SCT2F

The new RotoLock series of adapters from William Optics may well set the "gold' standard for visual backs and eyepiece adapters in the astronomy industry! Thoughtfully designed, exquisitely machined, and artfully presented, these adapters provide a very convenient and robust method to attach eyepieces and accessories to your telescope.

Just rotate the golden grip 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 that click every few degrees make this adapter a joy to use. The large, knurled grip ring is easy to grasp with gloves on as well.

This WO adapter # D-ROTO-A2-SCT2F has a 2" eyepiece holder on one side and a standard 2" SCT female thread (2"x24TPI) on the other side. Owners of all popular SCTs will find the 2" SCT Rotolock visual back to be the perfect way to add 2" capability to their scope. It directly mounts to the 2" SCT male threads on all popular 5 - 9.25" Celestron and Meade SCTs.
