Preorder now and receive a complimentary ZWO 0.75x F65RE flattener with the optical tube until July 31, 2023.

The ZWO FF65 APO is a professional-grade telescope designed specifically for astrophotography. Engineered with optimized structure and advanced optics, this equipment is ready to capture stunning images right out of the box without the need for additional accessories.

This telescope features an advanced apochromatic quintuplet design with an air gap. To ensure superior correction of chromatic aberrations, ZWO utilizes two low-dispersion (ED) glass elements, commonly found in high-end astrographs. Alongside exceptional color reproduction, the ZWO FF65 APO maintains minimal field curvature, resulting in distortion-free images even at the edges of the frame, without the requirement of an extra flattener.

In addition to its outstanding optical performance, the ZWO FF65 APO boasts top-notch mechanical elements known for their quality and precision. Its sturdy focuser enables the attachment of heavy astronomical cameras, while the CNC-machined mounting rings and Vixen foot provide stability to the tube.
