ZWO EFW 7x2"

FF107APO/FF130APO 0.7× Universal Reducer

ZWO has released a new 3-inch 0.7× full frame reducer that is compatible with the FF107APO and FF130APO telescopes. It has a three-element optical design, including one element made of ED glass. Its reduction factor is 0.7, which gives the FF107APO a shortened focal ratio of f/4.9 and a shorter focal length of 524mm. This allows for less total integration time and a wider field of view, bringing more convenience and possibilities for your wide-field deep sky imaging.

The reducer has a standard 55mm back focus and comes with M68, M54, and M48 threaded adapters for easy attachment.

FF80APO 0.76X Full Frame Reducer

ZWO has released a new 3-inch FF80APO 0.76X full frame reducer with a three-element optical design, including one element made of ED glass. Its reduction factor is 0.76x, which gives the FF80APO f/7.5 astrograph a shortened focal ratio of f/5.7 and a shorter focal length of 312mm. This allows for less total integration time and a wider field of view, bringing more convenience and possibilities for your wide-field deep sky imaging.

The reducer has a rear interface that attaches to the FF80APO telescope tube’s included four-segment camera extension tube. The back focus is the standard 55mm, and it has a built-in M48X0.75 2-inch filter thread for easy attachment.
