The stock focusers on many telescopes are simply not capable of supporting the weight of today's heavy image trains that can include a rotator, off-axis guider, filter wheel, camera, and more. This can cause the focuser to slip out of focus, or even worse: cause dreaded sensor tilt, which can be daunting to fix. The innovative team at William Optics has been hard at work trying to resolve this problem, and have now announced their patented solution: the William Optics Internal Focus Design, or WIFD for short. The WIFD is a revolutionary telescope design that moves the focuser from the rear exterior of the telescope to the inside. The WIFD focuser drawtube stays housed in the main chassis of the telescope, which results in a dramatically more stable focuser: The WIFD features a smooth rack and pinion design that is incorporated into the focuser to provide precise adjustability... See full list on agenaastro.com The included field rotator features smooth camera rotation with markings for degrees and a locking thumbscrew to prevent accidental camera movement. See full list on agenaastro.com The WIFD will not just be limited to the GT81, and will be adapted to many sizes of refractors. Additional optical designs are possible to meet various photographic requirements enhancing the line to include a number of apertures and fast focal ratios. Please note:The focuser travel does not extend over the full range of the markings shown on the telescope tube. This is normal in all WO WIFD/Pleiades telescopes and not a defect in your particular unit.
