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.  The user can enjoy the benefits of a traditional two speed fine focuser, while not worrying about limitations typically found in traditional rear mounted focusers. \u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0652\/6245\/2965\/files\/thenewwifd_480x480.png?v=1675873568\" alt=\"\" width=\"615\" height=\"260\"\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0652\/6245\/2965\/files\/WIFDfocuserdesign_480x480.png?v=1675873667\" alt=\"\" width=\"549\" height=\"263\"\u003e\u003c\/p\u003e\n\u003ch2\u003eINTERNAL FOCUSER DESIGN\u003c\/h2\u003e\n\u003cp\u003e\u003cspan\u003eNEW 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.  The redistribution of weight allows for better balance during imaging sessions.\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cp style=\"margin: 0px 0px 1rem; padding: 0px; color: #333333; font-family: 'Open Sans', Arial, 'Helvetica Neue', Helvetica, sans-serif; font-size: 17px; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; background-color: #ffffff; text-decoration-thickness: initial; text-decoration-style: initial; text-decoration-color: initial;\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0652\/6245\/2965\/files\/WIFDFOCUSER_480x480.gif?v=1675873830\" alt=\"\" width=\"627\" height=\"419\"\u003e\u003c\/p\u003e\n\u003ch2\u003eDESIGN PRINCIPLE\u003c\/h2\u003e\n\u003cp\u003eScalable Design.  The WIFD series will allow for many sizes and is not limited to smaller refractors.   Additional optical designs are possible to meet various photographic requirements enhancing the line to include a number of apertures and fast focal ratios.\u003cbr\u003e\u003cbr\u003eInspired by the tremendous success of the WO CAT series of astrographs, William Optics has advanced the capabilities of astrophotography to the next level with this “no weight limit on photo accessories” design.  The solid tube where accessories are attached, has a rigid design, and will not flex or exhibit any change in the optical path regardless of the weight of the camera and filter wheel attached to it.\u003c\/p\u003e\n\u003cp style=\"margin: 0px 0px 1rem; padding: 0px; color: #333333; font-family: 'Open Sans', Arial, 'Helvetica Neue', Helvetica, sans-serif; font-size: 17px; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; background-color: #ffffff; text-decoration-thickness: initial; text-decoration-style: initial; text-decoration-color: initial;\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0652\/6245\/2965\/files\/WIFDdesign_480x480.png?v=1675873934\" alt=\"\" width=\"640\" height=\"304\"\u003e\u003c\/p\u003e\n\u003ch2\u003eCAT DESIGN\u003c\/h2\u003e\n\u003cp\u003eImproved “CAT” design ring tubes and dovetail base are lighter while remaining equally rigid.
