William Optics RedCat 61 mm WIFD Petzval APO Refractor, in red

The William Optics RedCat 61mm WIFD Petzval APO is a remarkable compact optical device that delivers incredibly sharp, high-contrast, and detailed astrophotography images. Meticulously crafted with the finest materials available, this telescope guarantees exceptional performance.

At the core of this telescope lies the Petzval optical system. To achieve exceptional image quality, William Optics incorporated a low dispersion lens made from synthetic fluorite—an extraordinary optical material. Known as FPL-53, this material possesses a high Abbe number, ensuring superior color correction. Additionally, FPL-53 exhibits remarkable chemical stability compared to natural crystalline fluorite.

Setting itself apart from its counterparts, this telescope features the innovative WIFD (William Optics Internal Focus Design) focuser. This patented solution ensures perfect linearity, even when accommodating large reflex cameras or hefty astronomical cameras. Consequently, the risk of unwanted vignetting is minimized to zero, guaranteeing optimal image quality. Furthermore, the WIFD focuser is fully compatible with the WO EAF autofocus system, providing convenience and precision.

The telescope tube is securely mounted on meticulously designed clamps, equipped with a Vixen socket for attaching a finder or guider. This practical feature adds versatility to the instrument.
