William Optics WIFD Telescopes

This innovative design combines a precision (patented) internal focusing mechanism with premium apochromatic optics.

Designed to handle the newest generation of large, heavy, high-resolution cooled cameras.

The focuser is integrated inside the main tube assembly, so no focuser drawtube movement is visible from the outside. Enjoy the benefits of a traditional two-speed fine focuser without the limitations found in conventional rear-mounted focusers.
