The ZWO FF65 APO is a refractive astrograph with the powerful flatfield optical design which saves you from the expensive cost of a field flattener. It eliminates the trouble of calculating the back focus distance of the flattener and connecting various accessories to achieve that distance. You can just connect any possible accessories you need. As long as the target is focused, the whole optical system is perfect for imaging. This makes the whole setting up process much more convenient, and saves your time, allowing you to pay more attention to the image shooting itself.

The FF65 APO is also a nice choice for your visual observation. It fits diagonals as well as various eyepieces and can achieve a perfect focus, and can even be used to observe planets with a super-high magnification eyepiece.

The whole design of the telescope is compact and lightweight. The OTA weighs only 2kg, and the full package with tube rings and other accessories weighs 2.8kg. It has an aperture of 65mm. The focal ratio is f/6.4 and focal length is 416mm. Instead of the quadruplet structure of other ZWO FF APO telescopes, the FF65 APO is a quintuplet with two ED glasses which offers excellent control of chromatic and other aberrations.

The FF65 APO supports the full-frame imaging circle and has a fine spot diagram with tiny distortions of the peripheral stars. The 2.5″ rigid focuser comes with a new-type 360° rotator with scales and a finder base. M68, M54, and M48 camera adapters are also attached, and the M48 adapter has a 2″ female thread for installing filters.
