William Optics 3.5 Rotator Rotolock Visual Back

William Optics 3.5 - Sturdy and quick attachment for your eyepieces

The William Optics 3.5 Rotolock makes changing eyepieces easy and secure. You lightly tighten the ring, and your eyepiece is immediately firmly in place. No tilt, no play. Everything stays nicely straight, keeping your image clear and sharp.

Ease of use without hassle

With the Rotolock, you don't have to clamp or unscrew anything. You just turn, and the system clamps evenly all around. This gives you more confidence, especially when you change eyepieces more frequently while observing.

Perfect for the large FLT refractors

You screw the adapter directly onto the 3.5″ focuser of your FluoroStar. On the eyepiece side, you get a generous 2″ opening. So you can use all your favorite eyepieces and accessories without restriction.

Strongly built and available in multiple colors

The aluminum casing feels solid and remains vibration-free. You can choose from red, blue or gold, so your setup will look as good as it performs.
