William Optics 3.5 Rotator Rotolock Visual Back

William Optics 3.5 Rotator Rotolock Visual Back: 2-inch parking position on the large FluoroStar

The William Optics 3.5-inch Rotolock visual back threads onto the 3.5-inch focuser of the large FluoroStar refractors and provides a generous 2-inch opening with a Rotolock clamping system on the eyepiece side. A quick twist of the locking ring and your eyepiece or star diagonal is clamped evenly all around: tilt-free, centered, and scratch-free.

The Rotolock principle works like a twist-lock: no loose clamping screws, changing is done with a single movement of the hand, even with heavy 2-inch eyepieces and with gloves on. This version is one of the three color schemes in which William Optics supplies this visual back.

For the large FLT refractors

Made for the 3.5-inch focusers and extension tubes of the William Optics FluoroStar line. This is how you use your complete 2-inch eyepiece and diagonal park on the largest WO tubes, without play in the chain.

Featured accessories
