Sky-Watcher 0.85x Reducer/Flattener for EvoStar 72ED

0.85x Reducer/Flattener designed specifically for the Sky-Watcher EvoStar 72ED refractor. The use of this reducer lowers the native 420 mm (f/5.8) focal length down to 355 mm (f/4.93), while also dropping exposure time by 38%. A thread-on mounting adapter is included.

Works with both APS-C and full frame sensors but is better suited for use with APS-C and smaller sensors. Field of view measures 5.8 x 3.87 degrees with a full frame camera and 3.79 x 2.53 degrees with an APS-C crop sensor. Contributes 55 mm of back focus.
