Introducing the WILLIAM OPTICS Internal Focus Design (WIFD) Apochromatic Series.

This innovative and revolutionary design combines a precision (patented) internal focusing mechanism with the highest quality optics available, providing the ultimate apochromatic refractor for astrophotography.

Designed from the ground up with the ability to handle the newest generation of large, heavy, high-resolution cooled cameras, the rock-solid optical tube assembly is uncompromised in quality. The movement of the focuser is integrated inside the main tube assembly, so there are no movements of a focuser drawtube visible from the outside.  Enjoy the benefits of a traditional two speed fine focuser, while not worrying about limitations typically found in traditional rear mounted focusers.

Internal Focuser

NEW internal focuser.  Our new design includes the Patented WO center focuser with precise internal sliding of fixed optics to prevent image shift. 

The integrated position viewing window on the focuser provides instant verification of the graduated numerical display.  The smooth rack and pinion design is incorporated into the focuser to provide super fine adjustability for critical focus.  The internal movement of the optical elements is protected from the elements and can’t come out of alignment.

    Note: You may need riser blocks to use the Pleiades 68 on some dual-saddle mounts. The focuser impacts on the Celestron Advanced VX and CGX mount saddles (we assume it will also impact the CGEM II saddle). The focus knob also impacts the iOptron CEM70 and GEM45 / CEM40 dual-saddle plates. The focuser knob does not impact the SkyWatcher EQ6 and HEQ5 mounts.
