William Optics Pleiades 111mm F4.8 Astrograph
William Optics introduce the latest in its range of innovative WIDF Instruments.
This innovative design combines a precision (patented) internal focusing mechanism and premium 7-element (Septuplet) apochromatic optics with FPL-53 glass.
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.
Featuring a 7-element (Septuplet) apochromatic design, the Pleiades 111 works at the fast focal ratio of F4.8 and provides a wide and flat field suitable for use with large sensors.
With a focal length of 528 mm, the Pleiades 68 provides a wide field of view and is ideal for widefield imaging.
Other features include a camera angle rotator and tilt adapter.
Fitting a ZWO EAF Motor Focuser
Please Note: William Optics are using a new lens cell design in this Pleiades series telescope that incorporates high-quality FPL-53 glass for superior optical performance. Before storing, please allow sufficient time for the optics to acclimatise to room temperature. The telescope must be thoroughly dry and free of moisture or dew (condensation) before storing. This ensures the safety and longevity of the telescope's components.
Always store the telescope at a consistent temperature and in a dry environment to prevent any potential damage to the optical elements. Remember to leave the tube uncovered and opened during the acclimatisation period. As always, taking appropriate care of your telescope will ensure its optimal lifespan.
