How does a field flattener work

WebA focal reducer works using a positive lens, which shortens the focal length by causing the incoming beam of light to converge more quickly. The shorter the focal length, the greater the focal reducer’s reduction factor when placed into a telescope’s optical path. This also decreases the effective focal ratio of the instrument.
