ZWO Reducer 0.75x for FF65 APO

The ZWO Reducer 0.75x for FF65 APO is specifically designed for the ZWO FF65 APO apochromatic refractor. This high-quality focal reducer shortens the focal length of the optics by a factor of 0.75, resulting in faster exposure times and capturing a wider field of view. Ideal for deep-sky astrophotography of extensive nebulae, star fields, or Milky Way structures.

This reducer is optically fully optimized for the FF65 APO, ensuring a flat and sharp image across the entire field, even when using full-frame or APS-C cameras. Thanks to the included adapters with M48 and M54 threads, the reducer can be flexibly used in various astrophotography setups.

With a 2 “insertion size and integrated filter thread, you can easily use standard 2” filters — without additional adapter rings or compromising image quality.
