More information

  • ZWO FF65-APO - Overview

    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 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.

    Quadruplet Air-Spaced APO

    The FF65 APO is a quintuplet with two ED glasses which offers excellent control of chromatic and other aberrations.
