Flattener/Reducer 0.8x

The reducer shortens the focal length of the telescope and is therefore also called a focal reducer. This makes the optics "faster" for photography and the image brighter. It also increases the field of view.

Since a stronger signal is captured in the same exposure time with a reducer, you can expect a higher signal-to-noise ratio and thus better detail in your images.

The flattener is a lens that evens out the field, as this is slightly curved by the primary optics.
