ZWO FF 80 APO Refractor Telescope (ZWO-FF80-APO)
Why we love the ZWO F80RE Reducer for FF80-APO (ZWO-F80RE)
Product Description
FF80APO 0.76x Full Frame Reducer
ZWO has also 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 456mm. 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.
Connection Steps:
- Prepare the FF80APO telescope tube and the focal reducer.
- Unscrew the four-segment connector at the end of the FF80APO telescope tube.
- Unscrew the end cap of the 0.76x reducer and attach it to the M68 thread of the four-segment connector.
- Unscrew the front cap of the reducer, insert it into the focuser inner tube, and tighten it.
