Reducer 0.7x

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 0.7x reduction gives the PHQ a larger aperture ratio of 1:4.9 instead of 1:7, resulting in a significantly shorter exposure time. The reducer is simply plugged into the focuser.
