Description

Thread this 3.5" to 2" Rotolock visual back adapter onto the rear of a William Optics FLT refractor with a 3.5" rack & pinion focuser to upgrade it for use with a 2" diagonal or other 2" accessories. This eliminates the need for compression rings. A supplementary 2" to 1.25" adapter is also available but does not come with this system. To lock and center an inserted 2" accessory in place, simply rotate the adapter ring clockwise. Rotate counterclockwise to remove the accessory. Installs in mere seconds! A mild clicking noise from the internal ball bearings indicate when the visual back is opening and closing, providing easy operation at night.
