William Optics 2" RotoLock Eyepiece Adapter/Visual Back
with SCT 3.28" Female Threads

If you own a large Schmidt-Cassegrain telescope and have been wishing for a way to upgrade your visual back to a William Optics RotoLock system, your wait is over. This is the William Optics 2" RotoLock Eyepiece Adapter/Visual Back with SCT 3.28" female threads. This RotoLock adapter will mount to the 3.28" SCT male threads on most popular large SCTs (including Celestron 11"-14" and Meade 10"-14" SCT telescopes). This product is a great way to upgrade your favorite large SCT and it will replace your original visual back with a 2" RotoLock model with the convenience and reliable hold provided by the RotoLock system. It will provide a full 2" clear aperture. It is also threaded for 48 mm filters.

This WO 2" RotoLock Eyepiece Adapter / Visual Back has a female 3.28" SCT thread on one side and a standard 2" visual back on the other side. Simply unscrew the original eyepiece holder visual back from your SCT scope and screw on this William Optics 2" RotoLock Eyepiece Adapter in its place. Your scope is now upgraded to the WO RotoLock system.

Just rotate the adapter ring clockwise a small amount to lock any inserted accessory, or counter-clockwise to release the accessory. William Optics' 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.
