Ultra-Cat 76

The Ultra-Cat 76 is a high-performance 76mm apochromatic refractor designed for astrophotographers who demand exceptional clarity and true color accuracy, featuring a 5-element advanced Petzval optical design with super ED and lanthanum glass and a fast f/4.8 focal ratio that delivers stunningly sharp, flat-field images across its 50mm image circle. Optimized for Full Frame, APS-C, and M4/3 sensors, it also offers compatibility with Medium Format cameras for outstanding wide-field astrophotography. The patented WIFD focusing design relocates the focuser to the center of the telescope, eliminating tube tilt caused by the weight of cameras and accessories, and by removing the need for a traditional rear drawtube, the optical path remains fully unobstructed. This limited edition of 100 units worldwide combines uncompromising astrophotography performance with a symbolic anniversary finish, featuring a unique laser-engraved emblem of a cat embracing "30" and personally hand-signed by founder William Yang on the lens cover.
