William Optics RotoLock 3.5” Visual Back
- Add this amazing Rotolock Visual Back to the FLT 3.5" focuser and say goodbye to compression rings!
- Once installed (it takes seconds!) just rotate clockwise to tighten and center a 2" accessory, and rotate counter-clockwise to release. Check out the video below to see the RotoLock Visual Back in action!
- The gentle click of the internal ball bearings offer an audio clue when opening and closing the visual back, making it easy to operate in the dark, and the ribbed exterior offers a good grip.
- The William Optics RotoLock Visual Back threads onto the back of an FLT telescope with a 3.5" focuser, and presents a 2” opening for your diagonal, camera, or other accessories. A 2" to 1.25" adapter is available, but not included in this package.
