Make your diagonal directly compatible
The William Optics SC adapter lets you quickly adapt your Dura Bright 90° diagonal for telescopes with SC threads. You unscrew the original socket and put this adapter on. That's it. You don't have to adjust or readjust anything. This way you connect your diagonal directly to more telescopes, without additional parts.

Firm attachment without fuss
The SC thread ensures a firm, stable connection. Your diagonal stays straight, even when using heavy eyepieces. That means your image stays steady and you don't have to keep re-pointing. You change faster, work easier and keep more time to really look.
Light, strong and built for long sessions
The adapter is made of aluminum. That makes it light, but also sturdy enough for intensive use. You can unscrew and tighten it often without wear and tear. This keeps your setup reliable even during cold nights or long observations.
