William Optics M63 Flat6AIII Adapters for Flattener

Easy connection for your flattener

The William Optics M63 Flat6AIII adapter makes it easy to fit your Flat6AIII to a 2″ focuser. You simply slide the adapter into the focuser and tighten it. No fuss. No loose parts. Everything feels solid and fitting right away.

Reliable mounting for a flat image

The M63 connection keeps the flattener exactly in line with your optics. This gives peace of mind to the image. The stars at the edges stay tight. You get an image that is equally sharp everywhere, so you spend less time post-processing.

Additional convenience with filter thread

The 2″ connection has a built-in 48 mm filter thread. You screw your filters directly onto the adapter. This saves time and prevents incorrect combinations. This keeps your setup compact and everything works together smoothly.

Perfect for refractors in the 70-100 mm class

This adapter is made for refractors that operate between f/6.5 and f/8 and have a 2″ eyepiece mount. So you use it on many APOs in this range. This way you get the most out of the Flat6AIII without having to search for complicated intermediate pieces.
