ZWO FF80-APO 80 mm F/7,5 quadruplet

Preorder - The ZWO FF80 APO telescope is now available for pre-order until July 31, 2023. As a bonus, ZWO is including a dedicated 0.76x F80RE flattener for free with the optical tube.

The ZWO FF80 APO is a top-of-the-line telescope designed specifically for astrophotography. Its optimized structure and advanced features make it the perfect tool for capturing stunning celestial images. With automatic field curvature correction and a four-element camera adapter, this telescope is ready to use right out of the box, eliminating the need for additional accessories.

This advanced telescope utilizes a four-element air gap apochromat design. To ensure the best possible correction of chromatic aberrations, ZWO has incorporated two elements made of low-dispersion (ED) glass, a feature typically found in high-end astrographs. In addition to exceptional color reproduction, the ZWO FF80 APO maintains an incredibly flat field, resulting in distortion-free images even at the edges of the frame, without the need for an extra flattener.

The ZWO FF80 APO not only boasts exceptional optical performance but also exhibits high-quality and precise mechanical elements. Its robust focuser can accommodate even the heaviest astronomical cameras, while the CNC-machined mounting rings and Losmandy foot guarantee stability and reliability.
