Sky-Watcher


 

The Sky-Watcher 0.77x Flattener/Reducer for Esprit 120ED telescopes shortens the focal ratio of the 120ED to f/5.4 and focal length to 647mm. Exposure time is reduced by 68% when compared to the native f/7 configuration.

The illuminated and corrected image circle is 34mm, making it suitable for use with APS-C sensors and smaller.

The flattener/reducer has a back focus requirement of 95mm (55mm when paired with the included spacer and M48 adapter), making it possible to connect a wide range of imaging trains. Built-in 2" filter threads allow you to add light pollution filters with ease.
